Abstract :
The high speed on-off electromagnetic valve is an important component of pneumatic products, and is the key of electro-pneumatic interface. Based on detailed analysis of the circuit and mathematics model of the electromagnetic valve, the developed PWM control method is presented and the principle and implement of this method are discussed in this paper. At last, one of its applications, the pressure regulating valve, is introduced.
