研究具有时变采样周期网络控制系统的执行器失效的完整性问题.假设系统任意两个连续采样间隔具有上界,利用输入时延法,将时变采样周期网络控制系统等价转化为连续时变时延网络控制系统.在此基础上,基于时延条件,应用Lyapunov稳定性理论和线性矩阵不等式(LMIs)方法证明了鲁棒容错控制律的存在条件,设计了鲁棒容错控制器,并给出了系统完整性条件下的最大允许时延的估计方法.仿真结果验证了所提方法的可行性和有效性.
To study the integrity of actuator failure with networked control system with time-varying sampling period, suppose that the system has two upper bounds for any two consecutive sampling intervals and the input delay algorithm is used to convert the networked control system with time-varying sampling period into continuous Based on the delay conditions, the existence conditions of the robust fault-tolerant control law are proved by using the Lyapunov stability theory and the linear matrix inequality (LMIs) method, and a robust fault-tolerant controller is designed. The method of estimating the maximum allowable delay under the condition of system integrity is given.The simulation results verify the feasibility and effectiveness of the proposed method.
