【摘要】 针对多模型对象控制系统,基于遗传算法对PID控制参数进行寻优,分别建立不同工况下的模型,提出了以不同模型下的ITAE(时间乘以误差绝对值积分)性能指标加权和作为遗传算法目标函数的方法,寻优出一组最佳的PID控制参数,使得该参数在不同的对象模型下均表现出良好的调节品质,具有一定的实用价值。更多还原

【Abstract】 This paper introduce that how to search the PID optimized parameter to polytypism object control system based on genetic algorithm.We established model in different industrial instance and brought forward method of weighted sum of guide line of ITAE performance qua the target function of genetic algorithm.Through this way,we can found the optimize control parameter of PID and let this parameter represent well modulatory quality.This method have definite applied merit.更多还原
