基于模糊PID控制的燃气调压系统设计

Design of Gas Pressure Regulation System Based on Fuzzy-PID Controller

针对燃气管道压力难以控制的问题,将常规PID控制和模糊控制相结合,提出一种基于模糊PID控制器的燃气管道压力控制方案。通过与常规PID的压力仿真曲线相比较表明:模糊PID控制性能优越、超调量小、上升时间快、调整时间短。

In the gas regulator station automatic monitoring system,it is hard to control for gas pipe-line pressure. Based on conventional PID control and fuzzy control, the concept and design of the fuzzy PID controller are presented to control gas pipeline pressure. The simulation results indicate that Fuzzy PID controller has superior performance, less overshoot, quicker rise time and shorter adjusting time com-paring With routine controller.
