摘　　要：混沌优化方法是一种新兴的优化方法,它利用混沌系统具有的随机性、遍历性和对初值的极端敏感性等特点实现优化搜索,尤其对目标函数不可微、不连续的多参数寻优问题十分有效。把变尺度混沌优化方法引入到PID控制器的设计中,对PID参数进行优化并用SIMULINK对优化结果进行了仿真。结果证明,变尺度混沌优化方法算法简单有效,所设计的PID控制系统具有响应快、超调小和控制精度高等优点,具有很好的实用价值。Chaos optimization algorithm (COA)is a new optimization method, which uses the stochastic property, ergodicity and sensitivity to initial value of chaotic dynamic system to realize optimization search ,and it is effective to multiparameters optimization which objective function is nondifferentiable and discontinuous. The mutative scale chaos optimization algorithm,was introduced to design of PID controller based on mutative scale chaos optimization algorithm, the simulation instances show that the new method is simple and effective to realize PID control systems, which is fast reaction, small overshoot and high precision.
