摘　　要：提出了一种基于粒子群优化算法的H∞混合灵敏度控制律设计方法。该方法采用粒子群优化算法来优化加权函数,用H∞混合灵敏度方法设计飞行控制系统鲁棒控制器,满足了系统时域和频域性能要求。以某型飞机横侧向运动为例进行仿真,结果表明,用该方法设计的飞行控制系统具有良好的鲁棒性能和稳态性能,而且具有很好的动态品质。A design method of H∞ mixed-sensitivity synthesis flight control law based on PSO algorithm is presented. In this method, PSO is used to optimize the weighting functions, so the robust controller meets the time and frequency domain indexes. The digital simulation for a lateral motion of a aircraft is given. The results show that the flight control system designed with this method is not only good in robustness and stability, but also has a good dvnamic auality.
