6、可靠控制問題。然而，上述研究均未涉及同時考慮靜態(tài)輸出反饋控制形式和保性能指標，研究線性系統(tǒng)的可靠控制設(shè)計問題。將保性能指標考慮在控制器的設(shè)計中，基于Lyapunov穩(wěn)定性定律，LMI技術(shù)，執(zhí)行器故障處理法，推導出了基于線性系統(tǒng)下，靜態(tài)輸出反饋保性能的可靠控制器存在的充分條件，在該保性能可靠控制器下，無論執(zhí)行器件是否發(fā)生故障，均能保證系統(tǒng)漸進穩(wěn)定且滿足保性能指標。最后通過無人機實例仿真，繪制系統(tǒng)的狀態(tài)響應(yīng)曲線，驗證了該控制器的切實可行性。
