應用可變結構法於輸入具有非線性限制之飛彈系統的容錯控制研究

Abstract

本篇論文應用可變結構控制理論研究輸入具有非線性限制的容錯控制器設計，所設計的容錯控制器在控制輸入具有非線性限制時能確保系統之穩定運作。同時，本論文也利用變數變換解耦的原理設計錯誤偵測與診斷觀測器，成功的偵測與診斷致動器發生故障或異常情況以提供主動容錯控制之用。本論文也將所設計之主動及被動容錯控制器用於飛彈系統(HAVE DASH II)側彎控制之研究上，由模擬結果驗證了容錯控制器之可行性。

This thesis addresses the fault-tolerant controller design issues. By employing the Variable Structure Control technique, the output tracking performance of the system, whether faulty or not, are shown able to be achieved in spite of a constraint of input nonlinearity. In order to perform the active reliable control, an observer is also designed to detect and diagnose the actuators operating situations. Finally, the designed reliable laws are applied to bank-to-turn mission of a missile system. Simulation results demonstrate the effectiveness of the design.
