摘要 This paper proposes an observer-based output tracking control via virtual desired reference model for a class of nonlinear systems with time-varying delay and disturbance. First, the Takagi–Sugeno fuzzy model represents the nonlinear system with time-varying delay and disturbance. Then we design an observer to estimate immeasurable states and controller to drive the error between estimated state and virtual desired variables (VDVs) to zero such that the overall control output tracking system has H∞ control performance. Using Lyapunov–Krasovskii functional, we derive sufficient conditions for stability. The advantages of the proposed output control system are (i) systematic approach to derive VDVs for controller design; (ii) relaxes need for real reference model; (iii) drops need for information of equilibrium; (iv) relaxed condition is provided via three-step procedure to find observer and controller gain. We carry out simulation using a continuous stirred tank reactor system where the effectiveness of the proposed controller is demonstrated by satisfactory numerical results. 本論文對具時變延遲與干擾之非線性系統提出以估測器為基礎之輸出迴授控制,並以虛擬參考變數產生參考信號。首先,以TS模糊模型表示具時變延遲與干擾之非線性系統。再以估測器重建無法量測之狀態,使得控制器以H∞效能追蹤虛擬參考變數,將誤差信號趨近零。其中以Lyapunov-Kravoskii 泛函,推得穩定之充分條件,並進一步化為線性矩陣不等式。最後利用連續攪拌槽式反應器為例,執行模擬驗證,結果得以印證理論之推導。
