摘　　要：多模型控制器是解决复杂非线性系统的控制问题的一个十分有效又易于实现的方法。针对化工过程连续搅拌釜的数学模型,在不同的工作点设计多个线性模型逼近被控对象的动态特性。并在此基础上,基于模糊控制器的设计原理,设计模糊多模型控制器,并对控制器的性能进行分析。仿真研究表明,此模糊多模型控制器作用于连续搅拌釜这个复杂的非线性被控对象,能够使系统的输出很好跟踪设定值。The controller based on multiple models is a very effective and available tool for the control of nonlinear system. According the state equation of a chemical industry process-continuous stirred tank reactor （CSTR）, multiple linear models were designed to approximate the dynamic character of the system. Based on these multiple models, a multi-model controller was formed by using fuzzy principle. The property of this fuzzy multi-model controller was analyzed in different aspects. From simulation, it can be seen that the fuzzy multi-model controller can force the output of the CSTR system to trace a set-point value very well.
