An Off-Line Reference Management Technique for Constraint Fulfillment

Abstract

This paper considers an off-line reference management technique for constraint fulfillment. The proposed finite dimensional optimization program provides the managed reference signal which assures infinite-time constraint fulfillment. The main idea is to restrict the state variable at the final instance of finite-time reference management to a certain invariant subset of the state space such that fulfilling constraints for the primary designed closed-loop system is equivalent to restricting the state dynamics to this set. The proposed technique also, enables us to improve the control performance of systems with constraints. The control scheme is proved to fulfill the specified state and control constraints and shown to improve the set-point tracking performance.
