A New Approach to Improve the Matched Responses of High-Speed PWM Mode Electropneumatic Actuators

A new approach to improve the matched responses of high-speed PWM mode electro pneumatic actuators is introduced. By modifying the control signal, the matched responses are highly improved. For testing this new approach, an instrument is designed and developed. And the effectiveness of the approch is proved by experiment. The block diagram of the instrument is also presented.
