Performance Comparisons of PID and Fuzzy Logic Controllers of DC Motors

为比较比例积分微分控制器和模糊逻辑控制器控制直流电机的性能,本文从构建直流电机的数学模型入手,分别对传统的PID控制器、Ziegler-Nichols(Z-N)回路整定技术调整PID控制器和模糊逻辑控制器控制直流电机的性能进行了实验仿真。结果表明,与传统的PID控制器、Z-N回路整定技术调整PID控制器相比,模糊逻辑控制器具有更好的控制效果。

To compare the performance differences between PID and fuzzy logic controllers of DC motor,this paper establishes the mathematical model of direct current（DC）motors,and simulates the performance of two methods that control the DC motor using the traditional PID controller,the PID controller with Ziegler-Nichols（Z-N）based loop regularization technique,and fuzzy logic controller,respectively.The simulated results indicate that the fuzzy logic controller can achieve better effectiveness than other two PID controllers.
