Reliable Robust Tracking Control against Actuator Faults

摘要

In this paper we provide a solution to the reliable robust tracking problems against actuator faults. First, a more practical model of actuator faults than outage is adopted. Then a reliable robust tracking controller design method is developed. This method is based on the linear quadratic (LQ) tracking performance indexes and multiobjective optimization. A new formulation in terms of linear matrix inequalities(LMI) is adopted without introducing additional conservativeness. A given LQ bound of the actuator failure cases is guaranteed and the performance in the standard case is optimized. An example is given to illustrate the proposed design procedures.
