| 摘 要： | 针对一类具有下三角形函数控制增益矩阵的非线性系统, 基于滑模控制原理, 并利用Ⅱ型模糊系统的逼近能力, 提出了一种直接自适应模糊滑模控制器设计的新方案. 通过引入积分型李雅普诺夫函数及逼近误差自适应补偿项, 证明了闭环系统是全局稳定的, 跟踪误差收敛到零. 仿真结果表明了该方法的有效性.

| Abstract: | A new scheme of direct adaptive fuzzy sliding mode controller was proposed for a class of nonlinear systems with a triangular control structure. The design was based on the principle of sliding mode control and the approximation capability of the second type fuzzy systems. By introducing integral-type Lyapunov function and adopting the adaptive compensation term of optimal approximation error, the closed-loop control system was proved to be globally stable, with tracking error converging to zero. Simulation results demonstrate the effectiveness of the approach. |
