| Abstract: | The theory of fluid PWM technique is described and the mathematical model of the electro-pneumatic proportional valveis built. The scheme for the valve based on PWM technology is proposed. The digital proportional controller is designed withTMS320LF2407A singlechip and test is done. The test results show that the electro-pneumatic proportional valve based on PWMtechnology features smooth performance and conforms to the requirement by electro-pneumatic braking system. |
