چکیده

An infinite horizon controller is developed that allows incorporation of input and state constraints in a receding horizon feedback strategy. For both stable and unstable linear plants, feasibility of the constraints guarantees nominal closed-loop stability for all choices of the tuning parameters in the control law. The constraints’ feasibility Manuscript received September 20, 1991; revised March 9, 1992. The authors are with Department of Chemical Engineering, The IEEE Log Number 9208679. Paper recommended by Past Associate Editor, D. S . Bemstein. University of Texas at Austin, Austin, TX 78712. can be checked efficiently with a linear program. It is always possible to remove state Constraints in the early portion of the infinite horizon to make them feasible. The controller’s implementation requires only the solution of finite dimensional quadratic programs.

A new approach to stability analysis for constrained finite receding horizon control without end constraints

We present a new approach to the stability analysis of nite receding horizon control applied to constrained linear systems. By relating the nal predicted state to the current state through a bound on the terminal cost, it is shown that knowledge of upper and lower bounds for the nite horizon costs are suucient to determine the stability of a receding horizon controller. This analysis is valid f...

Receding Horizon Based Control of Disturbed Upright Balance with Consideration of Foot Tilting(RESEARCH NOTE)

In some situations, when an external disturbance occurs, humans can rock stably backward and forward by lifting the toe or the heel to keep the upright balance without stepping. Many control schemes have been proposed for standing balance control under external disturbances without stepping. But, in most of them researchers have only considered a flat foot phase. In this paper a framework is pr...

Feasibility and stability of constrained finite receding horizon control

Issues of feasibility and stability are considered for a nite horizon formulation of receding horizon control for linear systems under mixed linear state and control constraints. We prove that given any compact set of initial conditions that is feasible for the innnite horizon problem, there exists a nite horizon length above which a receding horizon policy will provide both feasibility and sta...

Offset-free Receding Horizon Control of Constrained Linear Systems

This paper addresses the design of a dynamic state feedback receding horizon controller, which guarantees robust constraint satisfaction, robust stability and offset-free control of constrained linear systems in the presence of time-varying setpoints and unmeasured disturbances. This objective is obtained by first designing a dynamic linear offset-free controller and computing an appropriate do...

A framework for robustness analysis of constrained finite receding horizon control

A framework for robustness analysis of input constrained nite receding horizon control is presented. Under the assumption of quadratic upper bounds on the nite horizon costs, we derive suucient conditions for robust stability of the standard discrete-time linear-quadratic receding horizon control formulation. This is achieved by recasting conditions for nominal and robust stability as an implic...

Stability of a truncated infinite constrained receding horizon scheme: the general discrete nonlinear case

-Some results concerning the constrained receding horizon formulation with infinite and truncated prediction horizon are presented. In this formulation a distinction is made between prediction and control horizons. The main result is a generalization of a known fact for linear systems, namely that, under certain technical requirements, the asymptotic stability of the above formulation holds for...
