This study addresses the finite-frequency robust feedback controller design problem against actuator faults for linear parameter-varying systems. First, a general model of actuator faults is presented. Then, sufficient conditions for the existence of the state-feedback controller are obtained by using generalised Kalman–Yakubovich–Popov lemma and projection lemma, which guarantee that the closed-loop...
In this paper a new LMI method is proposed for the strong γk-γcl H∞ stabilization problem. Due to the introduction of a new slack variable, it is expected to be less conservative than the authors' previous work. Furthermore, several recently developed methods can be seen as its special cases. Meanwhile the extended bounded real lemma proposed lately can be adopted to improve the LMI design results...
Different from the conventional constant anti-windup compensation compensator design, the proposed scheme in this paper depends on the time-varying parameters to reduce the conservatism in obtaining the best performance of the closed-loop system subject to actuator saturation. The estimation of the system performance under the given parameter-dependent compensation gain is also formulated to a linear...
