摘要
提出了一种基于MATLAB的模糊控制器综合优化设计与仿真分析的实现方法。该方法首先利用MATLAB中的模糊系统工具箱结合MATLAB函数构建控制规则可调整的模糊控制器,然后利用最优化工具箱优化模糊控制器的控制规则和参数,从而提高设计模糊控制器的效率。最后利用仿真连接器建立系统仿真模型并在单位阶跃输入信号作用下仿真分析系统动态性能和优化设计结果。仿真表明,控制规则及参数优化后,系统阶跃响应特性基本上能达到“快速—无超调”的设计目标。
It is presented in this paper a comprehensive optimization design and emulation analysis method of the fuzzy controller. The method based on MATLAB and digital simulation analysis includes three steps: firstly it uses fuzzy control system toolbox and MATLAB function to construct a fuzzy controller with adjustable control rules; secondly, it optimizes the control rules and parameters of the fuzzy controller by the optimum toolbox; thirdly, with the simulation linker, it builds an emulation model of a second-order system with delay and analyzes the dynamic characteristics of the whole system according to the step response. The simulation results show that the system can meet the target of quick and none-overshoot and design the fuzzy controller with high efficiency.
