模糊逻辑在PID参数整定中的应用

PID控制是最早发展起来的控制策略之一,由于受到参数整定方法烦杂的困扰,常规PID控制器参数往往性能欠佳,对运行工作情况的适应性差。本设计将模糊控制和PID控制结合起来,构建自适应模糊PID控制器,实现PID参数的最佳调整。该模糊自整定PID控制器既具有PID控制器高精度的优点,又具有模糊控制器快速、稳态特性。

Fuzzy logic tuning PID parameters based on Application

The PID control is one of the earliest developed one of the control strategy,because of the parameter tuning method of complex problems,the conventional PID controller parameters are often poor performance,running on the working situation of the poor adaptability.The design of fuzzy control and PID control is combined with adaptive fuzzy PID controller,construction,realize the PID parameter optimum adjustment.The fuzzy self-tuning PID controller with PID controller has the advantages of high precision,but also has the characteristics of steady state,fuzzy controller.
