为保证喷嘴流量试验台喷嘴入口压力恒定,提高喷嘴入口压力稳定性和控制精度,建立了试验台供油系统的传递函数,结合自整定模糊PID控制方法,利用Simulink软件进行仿真.结果表明:系统能够实现对喷嘴入口压力的有效调节.
In order to ensure the nozzle inlet pressure of the nozzle flow test bench constant and improve the pressure stability and control accuracy of the nozzle inlet, the transfer function of the test bench oil supply system was established and simulated by Simulink software combined with self-tuning fuzzy PID control method.The simulation results show that the system Effective regulation of the nozzle inlet pressure can be achieved.
