基于模糊理论与常规PID控制的模糊PID控制方法研究

模糊控制与PID控制是工业控制中两种常用的控制方法,然而,随着工业控制系统的复杂程度及对控制精度要求的日益提高,单一的模糊控制或PID控制已无法适应并满足控制系统对复杂程度和控制精度的要求。通过深入分析模糊控制和PID控制的各自优势及不足,提出将模糊控制与PID控制相结合的模糊PID控制方法,仿真实例表明,模糊PID控制方法能有效减小系统的超调量,提高系统的响应速度,缩短系统的调节时间,大大增强了控制系统的动态性能。

Research on Fuzzy PID Control Method Combined Fuzzy Theory and Conventional PID Control

Fuzzy control and PID control are often used in industrial control area. However, a single fuzzy control or PID control can not satisfy the need of the rising complexity and precision of control systems. This paper deeply analyzed the advantages and the disadvantages of fuzzy control and PID control, and proposed a new fuzzy PID control combined fuzzy control and PID control. The simulation results show that the proposed method can effectively reduce the overshoot of the control system, accelerate the response speed, and shorten the adjustment time, thus, the method can enhance the dynamic performance of the control systems.
