%X Power losses of a novel high speed hydraulic on/off valve including four transitions during its switching between on and off states are analyzed and modeled using mathematical equations related to the geometric parameters of the on/off valve and hydraulic system parameters. The dynamic response of the on/off valve is investigated by using feedback of axial position of the spool of valve which is driven axially by a gerotor pump. A fuzzy logic parameter self-tuning PID controller is used to overcome the system nonlinearity and simulation result shows that the overshoot is decreased greatly than conventional PID controller
