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

摘要

To achieve multiple performance requirements, a multi-con-strained 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, H_∞ 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.
