| 摘 要： | 提出了一种新的直升机执行机构故障状况下的可靠飞行控制律设计与仿真方法。建立了正常情况下和故障情况下的直升机数学模型。通过迭代线性矩阵不等式方法（ILMI）求解基于线性二次型的直升机可靠控制律,使得直升机在正常情况和故障情况下均能取得满意的性能指标。通过与标准线性二次型方法设计的最优控制律进行仿真比较,证明所设计的直升机可靠控制律安全有效。

| Abstract: | The reliable linear quadratic control for a helicopter with actuator failures was studied. The helicopter simulation model was introduced. The actuator fault models were established as well. A reliable linear quadratic control (RLQC) design algorithm was developed based on the iterative Linear Matrix Inequality (ILMI) approach. Simulation results demonstrate the effectiveness of the designed reliable controllers. |
