基于GUI的PID控制系统设计及实现

Design and Implementation of GUI-based PID Control System

采用了MATLAB R2013a软件,并结合自动控制原理及计算机控制技术等知识设计并实现了PID控制系统。所设计PID控制系统选取了较为典型的高阶系统、一阶时滞系统等2种以上典型工业系统模型进行仿真研究,用来评估系统控制性能优劣。同时,选用较为经典的连续PID控制算法(试凑法、Ziegler-Nichol曲线响应法和临界比例度法)对选择的被控对象进行PID参数整定,并比较了PID中各种控制规律(比例P、积分I和微分D)对控制系统品质的影响。所设计系统经过仿真及调试,测试结果表明所设计的基于GUI的单回路PID控制系统运行效果良好。

Using the software MATLAB R2013 a,implementation of PID control system is simulated,which combined with automation control theory and computer control technology.The design of PID control system selects the typical high-order system and the first-order time-delay plant for evaluating the control system performance. At the same time,three classical PID control methods is used to tuning PID controller parameters,and then compared different effects on the quality control system applying various laws of P,I and D in PID control system.
