Research on Control Characteristics of Cartridge Valve Controlled by High-Speed On/Off Valve
The operating principle of cartridge valve controlled by high-speed on/off valve is expounded, the mathematical models are established on the basis of the principle. The simulation model of system is created in AMEsim. By analyzing the curve charts of spool’s displacement and outlet flow rate of cartridge valve, the PWM signal frequency and duty cycle have influences on the control performance of cartridge valve controlled by high-speed on/off valve are concluded. The results show that the cartridge valve can be got good linear control when the input signal is low- frequency and moderate duty cycle.
