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.
