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(gòu)飛機要求其基本飛行控制系統(tǒng)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(tǒng)重構(gòu)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(tǒng),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(jié)果表明,這種控制器具有好的魯棒特性
