Pressure Close Loop Fuzzy Control Method of a Flow Adjustable Gas Generator

摘要:

为了改进流量可调燃气发生器的调节精度,引入燃气发生器压力闭环控制,针对流量可调燃气发生器压力闭环控制特点,在压力闭环中引入了模糊积分控制,此控制算法响应速度快,超调量较小,不同工况及长时间工作下系统仍然有较好的动态特性。 

Abstract:

In order to improve the accuracy of gas generator flow regulation for solid fuel ramjet, the pressure close loop control was designed. To reduce the pressure overshoot and to ensure the consistency of pressure changes, fuzzy integral control algorithm was designed. Simulation and experimental results show that this method has less pressure overshoot, faster response and better dynamic characteristic in different working condition.
