摘　　要：针对参数不确定飞机的颤振问题,采用粒子群算法优化鲁棒性能加权函数,用μ综合方法设计了飞机颤振抑制纵向控制律,并使用平衡截断法对所得到的控制器进行了降阶。仿真结果表明,采用μ综合方法设计的飞机颤振抑制纵向控制律具有较强的鲁棒性和指令跟踪能力。To suppress the Flutter of aircraft with model parameter uncertainty, the longitudinal flutter suppression robust control law of the aircraft is designed based on the μ- synthesis method, whose performance weighted functions are optimized by PSO, and the order of controller is reduced via balance truncation. In this paper, the robust performance weight functions are given. The simulation shows that the control law designed withμ- synthesis is stronger in robustness and follows the desire command response more precisely.
