基于Matlab的PID参数最优化设计

Optimization Design of PID Parameter Based on Matlab

PID参数的最优化设计通过单纯形法,利用Matlab的语句、图形功能、工具箱函数和最优化工具箱优化目标函数,构建动态系统,以简化动态仿真过程控制系统。多变量目标函数寻优用单纯形法,参数初值按控制理论确定,目标函数程序用仿真函数Sim编写。并以调节器参数最优化设计为例,论述了目标函数构造、初值确定、动态系统仿真分析的过程。

Optimization design of PID parameter is by simplex algorithm method, by using Matlab language, functional image, the function of Matlab toolbox and optimization toolbox to optimize object function and construct dynamic system, in order to simplify dynamic simulation process control system. Mult-variable object function is optimized with simplex algorithm method, the initial value of parameter is defined by control theory, object function program is compiled by simulation function-Sim. Taking optimization design of adjustor as an example, the process of constructing object function, defining initial value and simulating dynamic system was discussed.
