鲁棒可靠控制器的设计是容错飞行控制系统研究的重要内容,设计思想就是建立系统的正常情况下的模型和故障情况下的模型,根据Lyapunov稳定性定理求得反馈增益K,使得其能保证正常情况和故障情况下都能满足一定水平的指标要求。基于参数依赖Lyapunov方程和迭代线性矩阵不等式在直升机不确定性、H∞/LQ性能指标约束下提出直升机鲁棒可靠控制器设计方法,保证跟踪增广系统中内环系统的稳定性,通过仿真验证了该算法的有效性。 The design of a robust and reliable controller is an important part of fault-tolerant flight control system. The design idea is to establish a model of the system under normal conditions and a fault condition model. The feedback gain K is obtained according to the Lyapunov stability theorem so that it can guarantee Under normal conditions and fault conditions can meet a certain level of target requirements. Based on parameter-dependent Lyapunov equations and iterative linear matrix inequalities, a helicopter robust controller design method is proposed under the constraints of helicopter uncertainties and H∞ / LQ performance indexes to ensure the stability of the inner loop system in the tracking augmented system. The simulation results The effectiveness of the algorithm.
