摘要

摘要: 針對一類(lèi)具有外部擾動(dòng)的非線(xiàn)性系統, 提出了一種自適應模糊跟蹤控制方法. 首先, 利用模糊邏輯系統逼近系統未知的非線(xiàn)性函數, 并設計了一個(gè)模糊狀態(tài)觀(guān)測器來(lái)估計系統的不可測狀態(tài). 其次, 通過(guò)指定性能函數, 使系統的跟蹤誤差能夠約束在指定范圍內. 然后, 利用Backsteping方法結合包含對數函數的Lyapunov泛函, 設計了一個(gè)基于事件觸發(fā)條件的自適應模糊控制器. 基于Lyapunov穩定性理論和$\tanh$函數的性質(zhì)證明了所提出的控制策略能夠保證閉環(huán)系統中所有信號是半全局一致最終有界的. 最后, 通過(guò)一個(gè)數值仿真例子驗證了所提出方法的有效性.

Abstract: This paper investigates an adaptive fuzzy tracking control method for a class of nonlinear systems with external disturbances. Firstly, fuzzy logic systems and the fuzzy state observer are implemented to approximate unknown nonlinear functions and estimate the unmeasured states of systems, respectively. Then, the tracking error can be constrained within the specified range by means of the performance function. Furthermore, an event-triggered adaptive fuzzy controller is designed by employing the Backstepping method and Lyapunov functional with logarithm function. The proposed control strategy can ensure that all the signals of the closed-loop system are semiglobally uniformly ultimately bounded based on the Lyapunov stability theory and the properties of $\tanh$function. Finally, a numerical simulation example is provided to verify the effectiveness of proposed method.
