| Abstract: | In this article,the speed control system of D C motor regulated by single board computer is described,In the main circuit,the power source of D C motor is supplied by a PwM of large power transistor.The unipolar pulse modulation signal is applied to drivers of power transistors. The double-closed circuits regulations of speed and current of the system are implemented by the computer softwares.Analysis of inverse process of this system,as well as the program of the inverse process and the program of generated pulse-width modulation signal are described.A system with advantage of easy adjustment and high reliability is obtained. |
