摘要

针对一类非线性不确定组合大系统,利用模糊逻辑系统具有充分逼近连续函数的性质,分析和研究了这类系统自适应状态观测器设计问题,并在较弱的假设条件下,证明这种观测器与被控系统状态间的误差及各参数估计误差一致终极有界。最后的仿真实例说明了本文所提出方法的有效性。

Abstract

Based on fuzzy logic system with the properties of fully utilizing linguistic information from experts and approximating any continuous function with arbitrary, the states observer and adaptive laws are synthesized for a nonlinear composite large - scale system with uncertainties. Under some simple conditions, the laws and states observer make the states estimate error and parameters estimate error of the systems uniformly ultimately bounded (UUB). Finally, the simulation shows the validity of the method in this paper.
