Research of Magnetorheological Digital Flow Control Valve
A magnetorheological digital flow control valve is designed using magnetorheological fluid (MRF) magnetorheological characteristics. The paper gives the magnetorheological digital flow control valve’s structure and mathematical model, and according to the working condition, proposes using the pulse width modulation (PWM) control mode which is one of the digital valve control modes to realize the flow control. Simulation analysis has been done and the results show that the magnetorheological digital flow control valve has good static performance, high frequency switching speed and response，easy to realize intelligent control.
