Abstract:

This paper considers an approximate robust receding horizon control algorithm for a class of hybrid systems by exploiting the equivalence between piecewise linear systems and mixed logical dynamical systems. The control algorithm consists of two control modes which are a state feedback mode and a receding horizon control mode. In the receding horizon control mode, the constrained positively invariant sets are used as the end set constraint and the control law is obtained as an explicit form off-line. To reduce the computations we propose an algorithm that will determine the approximate solution by using orthogonal partitioning.

1 Introduction

In recent years, model predictive control (receding horizon control) has attracted the attention of researchers [1]. Bemporad et al. have proposed the explicit controller for receding horizon control problems to reduce the computational complexity of on-line optimization [2]. This result is a breakthrough in the research of receding horizon control. The generalization of the problem is reported [3], [4] and the sub-optimal problem is developed [5]. Further it is well known that, in the practical applications, the control law is required to guarantee that the closed-loop system fulfills constraints. The robustness is important since when disturbances or model mismatch are present closed-loop performance can be poor with likely violations of the constraints and no convergence can be guaranteed. For the issue the terminal penalty and constraints play important role [6]. In [7] feedback min-max model predictive control for linear time invariant discrete-time systems is proposed and the control algorithm which guarantees a convergence to the invariant set with no constraint violation. On the other hand, hybrid systems arise in a large number of application areas, and are attracting increasing attention. The hybrid system framework allows to model a broad class of systems arising many applications and to address the cooperative control problems and reconfigure problems [8]. It is known that a class of hybrid models can be described by the piecewise linear systems.
