| 中文摘要:针对一类定常线性系统，基于线性矩阵不等式（LMI），给出梯形区域（垂直条形与广义扇形区域结合）控制器和可靠控制器的设计算法。利用比离散故障模型更具有普遍意义的连续故障模型，给出确定状态反馈可靠控制器存在的充分条件，通过求解LMI，确定状态反馈的可靠控制器的参数矩阵。由所设计的可靠控制器构成的闭环系统能够抵御执行器发生的故障，使闭环系统的极点始终保持在所指定配置的梯形区域内。一个数值例子说明所给出方法的有效性及可行性。 |

| Abstract:For a class of invariant linear systems, not only we give the approach to design a state-feedback controller for trapezoidal regions（vertical bar area and generalized fan area）based on LMI(Linear Matrix Inequality), but also a state-feedback reliable controller for trapezoidal regions. A more practical continuous model of sensor and actuator failures than discrete model is considered, we present the sufficient condition for existence of the state feedback reliable controller. By solving the LMI, determine the parameter matrix of the robust reliable controller. The reliable controller given can against the influence of actuator failures and achieve pole placement in the trapezoidal regions. A numerical example is given to show the effectiveness and the feasibility of the obtained results. |
