| 中文摘要: |
| 针对线性系统，研究了考虑传感器增益故障情况下，静态输出反馈可靠控制设计问题。首先，在不考虑故障时，设计控制器，给出了系统保持渐近稳定的充分条件；然后，基于传感器故障，在原有反馈控制器作用下系统无法保持稳定；接下来，利用凸组合方法处理故障，及采用求解LMI不等式的方法对静态输出反馈可靠控制器进行重新设计，使闭环系统在发生传感器增益故障时仍能保持渐近稳定；最后，通过数值仿真验证设计方法的有效性和可行性。 |
| 英文摘要: |
| For linear systems, the problem of reliable control design for static output feedback considering sensor gain faults is studied. First, when designing the controller without considering the fault, the sufficient conditions for the system to maintain asymptotic stability are given. Second, based on the sensor failure, the system cannot be stable under the action of the original feedback controlle. Third, the convex combination method is used to deal with the fault, and the static output feedback reliable controller is redesigned by solving the LMI inequality method, so that the closed-loop system can maintain asymptotic stability in the event of sensor gain failure. In the end, the effectiveness and feasibility of the design method are verified by numerical simulation. |
