摘    要:漆包机烘炉系统复杂,传统控制方法效果不佳,在常规PID(proportion-integral-derivative)控制器的基础上,利用模糊控制理论结合PID算法实现参数自整定,解决了常规PID参数设定的不确定性.应用齐格勒-尼克尔斯方法确定了PID控制器参数的初值,再运用模糊控制理论实现对PID控制参数的修正,从而得到满足要求的PID控制器参数.在Matlab环境下对设计控制器进行了仿真研究,结果表明,参数自整定模糊PID控制比常规PID更具良好的控制效果.

Abstract:The enamelling machine oven system is complex,and the effect of the traditional control method is not good.Based on a conventional PID controller,it used the fuzzy control theory,combined with the PID algorithm,to achieve the parameter self-setting and to solve the problem with the uncertainty of the conventional PID parameters.Ziegler-Nichols was applied to determine the initial value of PID controller parameters.Then,the fuzzy control theory was employed to revise PID controller parameters,and the PID controller parameters meeting the requirements were obtained.The design controller was simulated in the Matlab environment.The results show that the parameter self-setting fuzzy PID controller has better controlling effect than a conventional PID controller,and it can also reduce the cost to save energy and improve the economic benefits.
Keywords:self-tuning  proportion-integral-derivative (PID)  fuzzy  matlab
