Study on Mathematical Modeling and Response Characteristics of High-Speed Solenoid Valve

High-speed solenoid valve has been widely used in aeroengine control systems whose performances are affected directly by the response speed of high-speed solenoid valve.The establishment of its mathematical model is discussed and its response characteristics by simulation model which is run in simulink of Matlab are analyzed.Back stepping and segmentation method is used in the research of response characteristics,and this method is proved to be an accurate,fast to get the influences of parameters on the valve's response characteristics.
