One new microcomputer control technique used on switched reluctance motor driving system is put forward. The technique has speed adjusted advantages of both frequency changed asynchronous motor and direct current motor. Using it we can adjust the speed for all of the different power motors in high dependence and level smooth methods. The principle of operation of every part and the methods of hardware design and software flow about the control system are simply introduced in this paper. The controling core of the system is a single chip computer of 8098, it has simple structure, nimble controling hitch diagnosed and protection strong points. The whole system speed can be adjusted at a high accuracy, and it has a rapid move state response, so not only at present but also in the furture, the system will be a very strong speed adjusted driving system.
