摘　　要：介绍了MATLAB的仿真工具箱和模糊逻辑工具箱的基本功能、建模方法.详细阐述了模糊逻辑控制系统的3个重要组成部分:隶属度函数、逻辑运算和模糊规则的基本理论和方法,利用模糊逻辑工具箱提供的模糊推理系统GUI工具实现了模糊控制系统的设计.基于水流运行规律大滞后、非线性的特点,将模糊控制系统应用于渠道运行系统的控制.利用SIMULINK建立了渠道运行的模糊控制仿真模型,并实现了对系统的仿真.结果表明,与传统的P+PR控制相比,模糊控制使系统获得了更好的动态性能.The basic functions and molding methods are introduced of SIMULINK and FUZZY LOGIC which are MATLAB＇s toolboxes. The basic theories and means about membership functions, logical operations and fuzzy rules are expounded; they are fuzzy logic control system＇s three important parts. By using the graphical user interface （GUI） tools provided by the fuzzy logic toolbox, a fuzzy control system is designed. Considering the water＇s movement is large lag and nonlinear, the fuzzy control system is applied to control the canal＇s moving system. A fuzzy control simulation model of canal＇s moving process is built by using SIMULINK; and simulation of the system is realized. The result shows that the fuzzy control method makes the system to acquire good dynamic functions than traditional P＋PR control.
