Reliable Guaranteed Cost Control of Discrete-time Systems with Mixed Fault for Actuator
This paper is concerned with the reliable guaranteed cost control problem for discrete-time systems with mixed fault for actuator and a given quadratic cost function. A more practical and general model of actuator failure is presented. Mixed fault model is discrete fault model and continuous fault model coexist in a system, mixed fault model put the discrete and continuous fault model together effectively. The problem is to design a reliable guaranteed cost state feedback control law which can tolerate actuator mixed fault, such that the cost function of the closed-loop system is guaranteed to be no more than a certain upper bound. A su cient condition for the existence of reliable guaranteed cost controllers is derived via the linear matrix inequality (LMI) approach, and a design procedure of such controllers is presented. Furthermore, a convex optimization problem with LMI constraints is formulated to design the optimal reliable guaranteed cost controller which minimizes the upper bound of the closed-loop system cost.
