【摘要】 研究一类含有不确定参数的时滞系统的鲁棒容错 H_∞控制问题．提出了线性不确定时滞系统对传感器失效具有完整性的一个充分条件,并基于 LMI 给出了鲁棒容错 H_∞控制器的设计方法及步骤．所设计的控制器使得相应的闭环系统对一切时滞和所有允许不确定参数保持内稳定,且闭环系统从扰动到受控输出之间传递函数的 H_∞范数不大于给定的指标值．仿真实例和仿真结果验证了所提出方法的有效性．更多还原

【Abstract】 The problems of the robust fault-tolerant H_∞ control for a class of linear uncertain systems with time-delays and uncertainties are studied.The sufficient condition for linear uncertain time-delay systems possessing integrity against sensor failures is given,and based on LMI,the design methods are given,by which the closed-loop systems are kept internal stability and the H_∞ norm of the transfer function from the disturbance to the controlled output is reduced to a given level for all admissible uncertainties and positive constant delays.An illustrative example and simulation results show the effectiveness of the proposed design method.更多还原
