  • Second-Order Sliding Mode Control of a Perturbed-Crane
    • Authors: Vázquez C; Fridman L, Collado J, et al.
      Abstract: A five degrees-of-freedom overhead crane system affected by external perturbations is the topic of study. Existing methods just handle the unperturbed case or, in addition, the analysis is limited to three or two degrees-of-freedom. A wide range of processes cannot be restricted to these scenarios and this paper goes a step forward proposing a control solution for a five degrees-of-freedom system under the presence of matched and unmatched disturbances. The contribution includes a model description and a second-order sliding mode (SOSM) control design ensuring the precise trajectory tracking for the actuated variables and at the same time the regulation of the unactuated variables. Furthermore, the proposed approach is supported by the design of strong Lyapunov functions providing an estimation of the convergence time. Simulations and experiments, including a comparison with a proportional-integral-derivative (PID) controller, verified the advantages of the methodology.

  • Two-Stage Feedback Control Design for a Class of Linear Discrete-Time
           Systems With Slow and Fast Modes
    • Authors: Radisavljevic-Gajic V.
      Abstract: In this paper, we first review the new algorithm for the two-stage feedback controller design of linear discrete-time systems, and then provide conditions for its applicability. The design algorithm is specialized and simplified for a class of linear systems with slow and fast modes (multitime scale systems or singularly perturbed systems). The proposed design significantly reduces computational full-state feedback design requirements and provides independent and accurate feedback controller design techniques in slow and fast time scales. We present also conditions needed for applicability of the proposed two-stage design in two time scales. The power of the two-stage design lies in the fact that different types of controllers can be designed for different subsystems using the corresponding feedback gains obtained by performing calculations only with the subsystem (reduced-order) matrices.

  • Stochastic Sampled-Data Control for H ∞ Stabilization of Transport
           Reaction Systems
    • Authors: Rakkiyappan RR; Dharani SS.
      Abstract: This paper investigates the problem of stochastic sampled-data H∞ control for a class of parabolic systems governed by one-dimensional semilinear transport reaction systems with external disturbances. A sampled-data controller design is developed by introducing the time-varying delay in the control input signals. The m sampling periods are considered whose occurrence probabilities are known constants and satisfy Bernoulli distribution. Since discontinuous Lyapunov functional copes well with problems of sampled-data control systems, a discontinuous Lyapunov functional is constructed based on the extended Wirtinger’s inequality. With this new approach, sufficient conditions that guarantee the asymptotic mean-square stabilization of the considered systems and the L2-gain analysis are derived in terms of linear matrix inequalities (LMIs), which can be solved by any of the available software.

  • Nonlinear Model Predictive Control of Integrated Diesel Engine and
           Selective Catalytic Reduction System for Simultaneous Fuel Economy
           Improvement and Emissions Reduction
    • Authors: Chen P; Wang J.
      Abstract: The applications of diesel engines in ground vehicles have attracted much attention over the past decade for the reasons of outstanding fuel economy, power capability, and reliability. With the increasing demand of less greenhouse gas emissions, the current diesel engine fuel efficiency remains unsatisfactory partially due to the conflict between the engine fuel efficiency and engine-out NOx emissions. While advanced aftertreatment systems, such as selective catalytic reduction (SCR) systems or lean NOx trap, have been integrated to diesel engines for reducing the tailpipe NOx emissions, the integrated controls for coordinating diesel engine and SCR system to achieve high engine efficiency and low tailpipe emissions are still limited. The purpose of this study is to develop such an integrated diesel engine and SCR system control method using nonlinear model predictive control (NMPC) approach with both start of injection (SOI) timing and urea solution injection rate as the control inputs. Control-oriented engine models were developed to quantify the influences of SOI timing on engine efficiency and engine-out NOx emissions. Simulation results under US06 driving cycle demonstrate that, given the same catalyst size in total, the proposed controllers are capable of reducing total engine fuel consumption over the driving cycle by 9.36% and 9.50%, respectively, for lumped SCR system and two-cell SCR system, while maintaining high NOx conversion efficiencies and low tailpipe ammonia slip.

  • On the Observability and the Observer Design of Differential Pneumatic
           Pistons
    • Authors: Arteaga-Pérez MA; Gutiérrez-Giles A, Weist J.
      Abstract: In this paper, an observability analysis for differential pneumatic pistons is presented, together with the design and implementation of linear observers of the Luenberger type. To avoid as much as possible the knowledge of the system model parameters, the generalized proportional integral (GPI) approach is employed for the estimation of unmeasured variables. Experimental results show the good performance of the proposed scheme.

  • Discontinuous Projection-Based Adaptive Robust Control for
           Displacement-Controlled Actuators
    • Authors: Busquets E; Ivantysynova M.
      Abstract: Displacement-controlled (DC) actuation is a revolutionary fluid power technology which has been utilized on a broad range of applications demonstrating substantial fuel savings and significant performance improvements over traditional valve-controlled (VC) systems. In this paper, a nonlinear discontinuous projection-based adaptive controller is synthesized to achieve precision motion control of DC actuators. The controller is formulated to compensate for uncertain parameters through online parameter adaptation. Additionally, its structure allows for the inclusion of unmodeled nonlinearities such as friction and external loads and disturbances. Transient performance and tracking accuracy are also guaranteed in the presence of both parametric uncertainties and uncertain nonlinearities, and asymptotic tracking is achieved in the presence of parametric uncertainties. To evaluate the synthesized controller, a test bench comprising a large hydraulically powered end-effector was utilized. The actuator, a vane-type hydraulic motor is mechanically connected to a large robotic arm with a wide range of motion. Measurement results demonstrate that the synthesized controller achieves the aforementioned advantages while attaining a high degree of motion accuracy.

  • On the Energetics of a Mechatronic Elevator System
    • Authors: Chen K; Fung R.
      Abstract: The energy balance equation consisting of mechanical and electrical parts of a mechatronic elevator system is studied in this paper. The total input energy is equal to the mechanical and electrical energies, where a weighting factor should be added for the mechatronic system. The calculus of variation is implemented to find the minimum input electrical energy control (MIEEC) and minimum dissipation energy control (MDEC), which are compared and found to have the same results. From numerical simulations, it is confirmed to demonstrate that the energy balance equation must contain a weighting factor in a mechatronic system.

  • Linear Vehicle Dynamics of the TowPlow, a Steerable Articulated Snowplow,
           and Its Kinematics-Based Steering Control
    • Authors: Kang J; Velinsky SA.
      Abstract: The TowPlow is a novel type of snowplow, which consists of a conventional snowplow vehicle and a steerable, plow-mounted trailer. The system is used to plow two typical traffic lanes simultaneously. In this paper, a linear dynamic model is developed in order to investigate the dynamic behavior of this system and its stability limits. Dynamic simulations of various maneuvers are performed, and kinematics-based control is implemented to investigate performance of the trailer's corrective steering. The goal is to ensure that the trailer does not intrude into adjacent lanes during plowing operations while also ensuring that both lanes are sufficiently cleared. Even though the control input is obtained from kinematic analysis, which does not take forces and inertia into account, the simulation results clearly show that the corrective steering helps the TowPlow meet its performance goals.

  • Nonlinear Vehicle Dynamics and Trailer Steering Control of the TowPlow, a
           Steerable Articulated Snowplowing Vehicle System
    • Authors: Kang J, Burkett G, Jr; Bennett D, et al.
      Abstract: The TowPlow is a novel type of snowplow that consists of a conventional snowplow vehicle and a steerable, plow-mounted trailer. The system is used to plow two typical traffic lanes simultaneously. In this paper, a nonlinear dynamic model of the TowPlow is developed for longitudinal, lateral, and yaw motions. The model considers nonlinearity through a modified Dugoff’s tire friction model, tire rotation dynamics, and quasi-static load transfer. The model is verified through steady-state and transient tests on an actual TowPlow system. A new snow resistance model is developed to allow simulation of the TowPlow in snow clearing operations. Then, active steering control of the trailer axle is derived with the goal of improving safety and efficiency of the TowPlow. The comparison of the simulation results between the controlled system and the uncontrolled system for cornering, slalom, up and down hill, and split friction coefficient braking maneuvers clearly demonstrates the efficacy of active steering control for the trailer axle of the TowPlow.

  • Boundary Backstepping Control of Flow-Induced Vibrations of a Membrane at
           High Mach Numbers
    • Authors: Sezgin A; Krstic M.
      Abstract: We design a controller for flow-induced vibrations of an infinite-band membrane, with flow running across the band and only above it, and with actuation only on the trailing edge of the membrane. Due to the infinite length of the membrane, the dynamics of the membrane in the spanwise direction are neglected, namely, we employ a one-dimensional (1D) model that focuses on streamwise vibrations. This framework is inspired by a flow along an airplane wing with actuation on the trailing edge. The model of the flow-induced vibration is given by a wave partial differential equation (PDE) with an antidamping term throughout the 1D domain. Such a model is based on linear aeroelastic theory for Mach numbers above 0.8. To design a controller, we introduce a three-stage backstepping transformation. The first stage gets the system to a critically antidamped wave equation, changing the stiffness coefficient's value but not its sign. The second stage changes the system from a critically antidamped to a critically damped equation with an arbitrary damping coefficient. The third stage adjusts stiffness arbitrarily. The controller and backstepping transformation map the original system into a target system given by a wave equation with arbitrary positive damping and stiffness.

  • Delayed-Decomposition Approach for Absolute Stability of Neutral-Type
           Lurie Control Systems With Time-Varying Delays
    • Authors: Liu P.
      Abstract: The problem of absolute stability for a class of neutral-type Lurie control system with nonlinearity located in an infinite sector and in a finite one is investigated in this paper. Based on the delayed-decomposition approach (DDA), a new augmented Lyapunov functional is constructed and the delay dependent conditions for asymptotic stability are derived by applying an integral inequality approach (IIA) in terms of linear matrix inequalities (LMIs). Finally, numerical examples are provided to show that the proposed results significantly improve the allowed upper bounds of the delay size over some existing ones in the literature.

  • Frequency-Weighted Variable-Length Controllers Using Anytime Control
           Strategies
    • Authors: Ferri BH; Ferri AA, Runge GB.
      Abstract: This paper develops an optimal frequency-weighted strategy to design anytime controllers that can react to changing computational resources. The selection of the weighting function is driven by the expectation of the situations that would require anytime operation. For example, if the anytime operation is due to occasional and isolated missed deadlines, then the weighting on high frequencies should be larger than that for low frequencies. Low frequency components will have a smaller change over one sample time, so failing to update these components for one sample period will have less effect than with the high frequency components. Additional considerations explored in this paper are stability analyses, architectural issues, and transient management. Two examples are included that demonstrate the methodology.
