Because die common fault detection method for sensors, residual x2 test, is insensitive to gradual - change - fault detection, a kind of residual x 2 test based on moving subnormal state is presented, and its validity is testified by mathematical simulation results, as shown in figures 5. 2 through 5. 5. with regard to the lag of soft fault detection, a kind of system reconstruction tactic based on hierarchic alliance structure of federal filters is proposed. mathematical simulation results, as shown in figure 6. 10, show the validity of isolating fault by using the tactic
西北工業大學沁士學位論文們要一個研究指出常用的傳感器故障檢測方法?一殘差x 『檢驗法對漸變性故障檢測的不敏感性，提出一種基於移動偽正常狀態的殘差檢驗法，並通過數學模擬驗證該方法對漸變性故障檢測的有效性；提出一種基於遞階聯合濾波器結構的系統重構策略，並通過數學模擬驗證該策略對故障隔離的有效性。A non - linear feed - forward loop is used to realize the coordinated control between the two controlled variables at the two control ends at first. secondly, a constant ac voltage control is implemented for a short period after the ac fault removal. finally, a staggered recovery strategy for different hvdc subsystems is also adopted, with the restart time interval of them optimized using the steepest descent gradient search method
該協調恢復策略的三個特點是：在常規的控制器結構中加入一個基於準穩態工作點的非線性前饋迴路；在交流故障被切除后的一個短暫時間內，逆變側採用定交流電壓控制：對不同的直流輸電子系統採取一種漸進的恢復策略。
