The Study and Application of an Intelligent Method for Modify Parameter

提出一种智能化PID参数整定的方法,适用于工作在不同惯性场合的计算机PID控制系统。该方法通过对PID参数在偏差调节中的作用进行分析,提出了智能评估及PID参数自动修正策略,并使用模糊控制规则来描述该参数调整过程,实现参数自整定的目的。最后,本文在一个温度控制系统上应用该方法,验证了方法的有效性。

An intelligent method for parameter regulating is proposed. With this method, the computer system using PID control algorithm can adapt to various situations. Different roles of PID parameters are analyzed in decreasing errors. Then an intelligent evaluation and automatic modification strategy is studied and implemented by fuzzy control rules. The application on a temperature control system show that the proposed method is valid.
