摘　　要：在MATLAB环境下,应用图形用户界面GUI开发了一个使用方便、实用性强的离散PID参数优化整定软件.以Ziegler-Nichols方法整定的PID参数作为寻优初始值,通过对ITAE准则目标函数求取最小值的方法对PID参数进行优化,从而实现了对PID控制器参数的优化整定.测试结果表明,应用本软件对PID控制器的参数进行优化后,可以使整个控制系统的动态性能得到显著提高.By applying the graphical user interface (GUI) and the optimal toolbox under the MATLAB environment, a practical and convenient software has been developed to meet the purpose of optimizing the parameters of a PID controller. With the parameters obtained from Ziegler-Nichols tuning as the initial value, a set of excellent PID parameters was gained by means of finding the minimum of an object function known as ITAE rule. Testing results indicate that the control system's dynamic characteristics can be improved observably after being optimized with the above method.
