飞机流量负载模拟系统复合控制策略研究

摘要

设计了飞机液压系统流量负载模拟,并推导出流量控制阀以及系统的数学模型.针对常规PID控制难以协调鲁棒性和快速性之间的矛盾,提出了自校正调节器与模糊参数自整定PID控制器相结合的复合控制策略,通过Matlab/Simulink仿真研究,验证了该方法能够有效提高流量跟踪性能和抗干扰能力.%The flow load simulation system of aircraft hydraulic system is designed, and mathematical models for the flow throttle valve and the whole simulation system are derived. As the conventional PID control system is difficult to reconcile the contradiction between robustness and fast, a composite control strategy using a combination of self-tuning regulator and fuzzy parameters self-tuning PID controller is put forward. The algorithm is simulated by using Matlab/Simulink. The simulation results show that the method can effectively increase flow tracking performance and robustness.
