| 研究传感器有故障的Delta算子线性不确定系统的鲁棒D–稳定问题, 旨在设计控制器以消除系统不确定性和传感器故障的影响, 确保闭环系统极点落在复平面指定圆盘区域内. 由于传感器故障具有连续的故障模型, 本文采用线性矩阵不等式(LMI)方法, 利用故障模型的结构信息, 得出了Delta算子系统状态反馈鲁棒D–稳定控制器存在的充分条件, 并由此提出相应控制器设计方法. 数值算例表明设计方法的可行性和有效性. |
| 英文摘要 |
| The robust D-stabilization is studied for the delta operator-formulated linear uncertain systems with sensor failures. The purpose is to design a controller which can tolerate sensor failures, such that the closed-loop poles always locate in a specified disk on the complex plane for all admissible uncertainties. Based on the linear continuous model of the sensor failures, the sufficient condition for the existence of a robust D-stabilization controller is derived via the linear matrix inequality(LMI) approach, and the design procedure is also presented. A numerical example is provided to demonstrate the availability of the design method. |
