Dynamic multi‐constrained output feedback controller design for linear discrete systems

Abstract

To achieve multiple performance requirements, a multi‐constrained dynamic output feedback controller is derived for linear discrete‐time systems. This paper addresses the problem of dynamic output feedback controller design subject to individual state variance constraints, H8 norm constraints, regional pole location constraints and minimum auxiliary entropy constraints. By solving the inverse solutions of a Riccati‐like equation, the present approach provides the conditions and solutions for the dynamic output feedback controllers to simultaneously achieve the above four performance requirements. A numerical example is also given to demonstrate the control effect of the present method.
