Abstract : the control reconfigurable aircraft with multi - surfaces needs robust basic flight control system to support enough time for failure detection and isolation . when partial surface loses , it can keep the damaged aircraft stable . in this paper , multivariable output feedback digital control laws are designed for the control reconfigurable aircraft ( cra ) . the method uses fast - sampling digital pi controllers to design digital flight control tracking system . this paper gives the way to design the controller and analyze its robustness characteristics . the simulation results indicate that the controller is very robust and the output responses are fully satisfactory 文摘:控制可重構飛機要求其基本飛行控制系統對舵面部分缺損故障具有強的魯棒特性,在故障發(fā)生后保證飛機的穩(wěn)定性,提供足夠的時間進行故障的檢測和隔離,為控制系統重構提供條件.本文采用高速采樣pi控制器設計輸出反饋跟隨系統,給出了控制器的設計方法,并分析了它對于控制舵面部分缺損故障的魯棒特性.仿真結果表明,這種控制器具有好的魯棒特性
