1混沌优化原理
混沌是在非线性系统中普遍存在的现象,混沌运动具有对初值的高度敏感性、运动轨迹的遍历性和随机性等特点,它能在一定的范围内按自身的规律遍历每一个轨道,既不自我重复又不自我交叉〔1〕.因此可利用混沌的这些特性,采用混沌变量进行全局搜索和寻优,可做到最优参数的设计.在混沌优化中采用Logistic方程作为变量的混沌运动.
结尾
针对PID控制参数整定繁琐的不足,设计了用于电锅炉温度控制系统的基于混沌优化的PID控制器.PID参数的优化利用了混沌运动的遍历性特点采用混沌粗搜索和细搜索相结合的方式得到了全局最优的PID控制参数,仿真结果表明该PID控制器超调小、调节时间短、无震荡,能够满足电锅炉温度控制系统的动态、静态性能指标
Therefore may use the chaos these characteristics,uses the chaos variable to carry on the overall situation search and the optimization,may achieve the most superior parameter the design.Optimizes in the chaos uses the Logistic equation to take the variable the chaos movement.Ending In view of the PID controlled variable installation tedious insufficiency,designed has used in the electric boiler temperature control system the PID controller which optimized based on the chaos.The PID parameter optimization used the chaos movement ergodicity characteristic to select the method which the chaos thick search and the thin search unified to obtain the overall situation most superior PID controlled variable,the simulation result had indicated this PID controller over modulation small,the control time short,did not have the shake,could satisfy the electric boiler temperature control system the tendency,the static state performance index
