摘要/Abstract

摘要： 采用MATLAB平台进行建模仿真的方法, 利用位置环/电流环双闭环比例-积分-微分(PID)控制系统, 并与模糊控制相结合, 解决了航空发动机燃油调节系统的旋转直驱阀(RDDV)伺服系统存在液动力负载扰动, 严重影响系统的动态特性和稳定性的问题. 仿真结果表明：在相同输入条件下, 采用模糊双闭环控制方法能在保证系统无超调的前提下显著缩短响应时间；当存在扰动时, 能使系统更快地恢复到稳态.

Abstract: The MATLAB platform was used for modeling and simulation, the position loop/current loop double closed-loop proportional-integral-differential (PID) control system, and the combination of fuzzy control were used to solve the problem of the rotary direct drive valve (RDDV) of the aero-engine fuel regulation system. The servo system had hydraulic load disturbance, which seriously affected the dynamic characteristics and stability of the system. The simulation results show that under the same input conditions, the fuzzy double closed-loop control method can significantly shorten the response time under the premise of ensuring that the system has no overshoot, when there is a disturbance, the system can be restored to a steady state faster.

Key words: rotary direct drive valve, double closed-loop control, fuzzy control, aero-engine
