Speed regulation with PWM for DC motor under one-cycle control

One-cycle control(OCC)1for PWM has been concerned and applied widely because of compactness, less devices and high speed of response, etc..The situation in speed regulation with PWM control of DC motor in onecycle control is investigated, the simulink simulation including open-loop and close-loop is carried out successfully.The high accuracy of steady regulation and fast dynamic response are proved.The traffic should be one of best selection because of simple circuit, less devices, compactness and high reliability.
