模糊自整定PID双闭环直流调速系统建模及仿真分析

本文章对于工程上常采用的直流调速控制系统,详尽地阐述了双闭环调速系统的PID控制原理,分别对调速系统的电流环、转速环的动态特性、抗干扰特性进行simulink仿真实验。针对在克服较大扰动和提高系统动态品质的要求,设计了一种基于模糊控制理论的PID控制器并对调速系统进行仿真实验。通过与原有PID控制器进行对比,发现基于模糊控制理论的PID控制器可以显著提升控制效果,并且具有非常强的抗干扰特性,快速的系统响应,良好的动态特性等。

Modeling and Simulation of Dual-closed Loops Speed Regulation System of DC Motor by：Fuzzy Self-tuning PID Controller

Aiming at the DC speed regulation system often used in project, this article elaborates the PID control theory of dual-closed loops speed regulation system, and makes the simulink simulation experiment to the dynamic characteristic and anti-interferencecharacteristic of the current loop in speed regulation system. To overcome larger disturbance and improve the dynamic quality of system, this article designs a PID controller based on fuzzy control theory for simulation experiment of speed regulation system. Compared with theoriginal PID controller, PID controller based on fuzzy control theory can greatly improve the control effect, has very strong anti-interference characteristic, fast system response, and good dynamic characteristics.
