动态输出反馈的少保守性NCS鲁棒容错控制
Robust fault-tolerant control of less-conservative dynamic output feedback in NCS
摘要
Abstract
The robust fault-tolerant control for dynamic output feedback networked control systems with uncertain time-varying delay and packet dropout were investigated.Without using the augmented state-space method to rebuild system model,by using Lyapunov-Krasovskii functional,the sufficient conditions for closed-loop networked control system with uncertain time-varying delay and packet dropout possessing robust integrity against actuator failures were given by adopting dynamic output feedback control law,and by using an improved separation lemma,the design problems of the robust fault-tolerant controllers were given via liner matrix inequalities.Finally,a numerical example was used to illustrate the effectiveness of the proposed method.The result shows that the less conservative method is obtained since the lower bound of the time-delay and appropriate free-weighting matrices being introduced,moreover without model transformation,scaling-up of cross terms and merging delays during the proof.关键词
