Electric performer is a major component of automatic control system. Considering that the high error ratio, poor quality and difficulty to maintenance, the Intelligence Research Department undertook the developing work of 獴 Series Stepping Electric Performers Apparatus)) , which was under grants by Liaoning Province Science and Technique Committee. And now we have successfully developed out a new electric performer by using computer, electronics, electricity, frequency-changing speed control, data communication and mechatronics techniques together.In the new electric performer, we used a Switched Reluctance Motor as servomotor. The S.R.M has many advantages itself, such as large outputting torque, high locational precision, non follow-up and self-braking and so on. The new electric performer apparatus adopted a whole new hierarchy. So it is more powerful, more reliable and it has a higher property price ratio than the old one. It can be used in manufacturing or process controlling system on electricity, petroleum, communication, mechinery and on many other areas.As a part of the whole research work, the thesis mainly introduce the control algorithm of the Switched Reluctance Drive system, developing of hardware and application in electric performers.
