中文摘要
      本文针对典型工业过程,通过在线辨识对象脉冲响应间接获取对象等效参数.利用按偏差积分准则离线优化整定出的PID参数与对象参数的关系,实现PID控制器的自校正.为抑制输出超调,提出了一种超前控制方法.仿真表明,该控制器对于交参数对象可获得满意的控制效果.
英文摘要
      In this paper,the plant parameters are indirectly obtained by identifying the weighting function of the Plant,utilizing the relations of plant parameter and off-linetuned optimum PID parameter according to IAE performance index,self-tuning PID control are realized. In addition,a method that using identified model to predict plant output,executing advance control for output overshoot is proposed.
