题目：Control Design with Guaranteed Transient Performance: an Approach with Polyhedral Target Tubes

报告人：王庆国教授，南非约翰内斯堡大学

摘要：In this seminar, a novel approach is presented for control design with guaranteed transient performance for multiple-input multiple-output discrete-time linear polytope difference inclusions. We establish a theorem that gives necessary and sufficient conditions for the state to evolve from one polyhedral subset of the state-space to another. Then we present an algorithm which, given a time-varying polyhedral set called the target tube, which may be specified from typical transient performance specifications, constructs an output feedback law that guarantees that the state evolves in this tube. Our formulation is very general and includes reference tracking with any desired transient behaviour in the face of disturbances, as specified, for example, by the most popular step response specifications. The approach is demonstrated by an example involving the control of water levels in two coupled tanks.
