摘 要:PID控制器由于结构简单、稳定、无静差等优点,在工业控制领域得到了广泛的应用。但在实际工业过程中往往存在很多不确定和非线性因素,当传统PID控制难以达到理想的控制效果。本文将模糊控制和PID控制方法相结合,改变控制器比例、积分、微分函数的参数以实现工业对象的优化控制并进行仿真研究。电机的实例仿真表明比普通PID控制方法精度高,超调量减少,具有较强的鲁棒性,减少系统稳态误差,微分作用可以提高响应速度以实现工业对象的优化控制并进行仿真研究。这种控制方法兼备模糊控制与PID控制优点,具有广泛的应用价值。4804

The Application Research of Fuzzy PID Control
Abstract:PID controller due to simple structure, stability, No Static poor advantages, has been widely used in the field of industrial control. There is often a lot of uncertainty and non-linear factors in the actual industrial processes, when the traditional PID control is difficult to achieve the desired control effect. Paper, fuzzy control and PID control method combined to change the the controller proportional, integral, differential function of the parameters to achieve optimal control of industrial objects and simulation studies. The instance simulation of the motor that high precision than the ordinary PID control method, the overshoot is reduced with a strong robustness to reduce steady-state error of the system, the derivative action can improve the response speed in order to achieve optimal control of industrial objects and simulation studies. This control method combines the advantages of fuzzy control and PID control has a wide range of applications.
