摘要
针对一类不确定线性系统,利用更一般、更实际的执行器出现混合故障的模型,设计可靠控制器的同时将系统的极点配置到指定圆盘内问题,混合故障模型是指在一个系统中同时包含离散故障模型和连续故障模型,并给出系统将极点配置到指定圆盘上可靠控制的充分条件.通过求解LMI(线性矩阵不等式)完成状态反馈可靠控制器的设计。仿真验证本文提出的设计控制器方法的可行性。
The reliable circular disk pole placement design problem of mixed fault model with actuator faiure for a class of uncertain linear systems is discussed.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,This controller designed to make the system less conservative,A sufficient condition of circular disk pole placement with mixed fault model reliable controller is given.State feedback controller is designed by solving LMI（linear matrix inequality）.A simulation example shows the efficiency in a system.
