| 摘 要： | 针对一类不确定非线性系统 ,基于一种修改的监督控制方案并利用广义多线性模糊逻辑系统的逼近能力 ,提出了一种模型参考自适应模糊控制器设计的新方案。该方案利用参考模型作为性能指标 ,自适应调节模糊控制器的规则库 ,并通过引入最优逼近误差的自适应补偿项来消除建模误差的影响 ,不但能保证闭环系统稳定 ,而且可使跟踪误差收敛到零。仿真结果表明了该方法的有效性

| Abstract: | Based on a modified supervisory control strategy and the approximation ability of generalized multilinear fuzzy logic systems (GMFLS), a new scheme called model reference adaptive fuzzy control (MRAFC) for a class of nonlinear systems is proposed in this paper. The MRAFC scheme employs a reference model to provide closed loop performance feedback for generating or modifying a fuzzy controller's knowledge base. The adaptive compensation term of optimal approximation error is adopted. By theoretical analysis, the closed loop fuzzy control system is proved to be globally stable, with tracking error converging to zero. Simulation results demonstrate the effectiveness of the approach. |
