Abstract:
For the pulse width modulation (PWM) high-speed on-off valve of a certain ramjet regulator, a simulation study on the system dynamic characteristics of pressure and flow rate during regulation of high-speed on-off valve was carried out by establishing a dynamic mathematical model of high-speed on-off valve system. The factors that influence the valve dynamic output characteristic were analyzed. The results indicate valve seat diameter, driving frequency and volume of control cavity are the main reasons that influence valve performance. The methods to improve the dynamic performance were provided. A reference is also provided for improving control system accuracy and performance in this paper.
