摘　　要：针对一类结构上具有相似性的非线性不确定复杂系统,利用模糊逻辑系统可以充分逼近连续函数的性质,研究这类复杂系统的鲁棒镇定问题,设计出了系统的全息鲁棒控制器和模糊逻辑系统参数估计的自适应律。为了简化控制器结构,在构造模糊逻辑系统时对被控系统的不确定性进行了归一化处理。在较弱的假设条件下,证明了这种控制器使被控系统的状态及参数估计误差一致终极有界,同时给出了误差的严密的数学分析。仿真实例表明所提出的方法是有效的。Based on fuzzy logic system with the properties of fully utilizing linguistic information from experts and approximating any nonlinear continuous function with arbitrary, the holographic robust control laws of nonlinear complex systems with uncertainties is discussed. By using the model of the complex systems and output information coming from the fuzzy logic system about uncertain factors, the holographic robust controller and adapitive laws of parameter estimate of fuzzy logic system are constructed. In order to eliminate the complexity of controller, the union process is carried out tin building the fuzzy logic system. Under some simple conditions, the laws and controller make the states of systems controlled and parameter estimate errors uniformly ultimately bounded (UUB), and the rigorous mathematical analysis about errors are deduced. Finally, the computer simulation shows the method validity.
