N2 - The electro hydraulic proportional valve is usually driven by the low frequency signal of PWM. However, the amplitude of chatter signal which proportional valve needs cannot be controlled independently. This is a big problem in the valve's application. In this paper, the driving theory of proportional valve is analyzed firstly. Then by deriving the driving current formula of proportional valve, the amplitude formula of chatter signal is obtained. At last, the method that compensation network is connected to the driving circuit of proportional valve is proposed. The method can bring independent control of chatter signalamplitude. The validity of the method is proved by digital simulation.
