PID与模糊控制算法的比较及其改进

Comparison and Improvement of the PID-control Algorithm and the Fuzzy Control Algorithm

分析比较了PID控制和模糊控制算法 ,针对一般PID控制容易产生超调、模糊控制的稳态精度不高的缺陷 ,提出了相应的改进算法—复合PID算法和带动态补偿的模糊控制算法 ,并通过水温控制仿真实验 ,比较了这几种控制算法的控制效果。实验结果证明 ,这两种改进算法不仅系统超调小 ,而且具有较高的稳态控制精度 ,可广泛应用于精确控制领域。

This paper analyzes and compares the PID control algorithm and the fuzzy control algorithm. Because the usual PID control method often appears super adjus and low precision of the fuzzy control method, we advance two improved control methods-the compound PID control algorithm and the fuzzy control algorithm with dynamic compensation. By the experiment, we get a group of control results of these control algorithm. These improved control methods have satisfied effect and can be widely used in exact control field.
