SPICE-assisted simulation of controlled electric drives: an application to switched reluctance drives

An example of simulation of a closed loop controlled electric device that shows the feasibility of simulating the equipment by means of a general-purpose electronic circuit analysis program is described. The SPICE program was used because of its well-known facilities for simulating electronic circuits. A method for extending the SPICE facilities to simulate the electromechanical energy conversion and the drive control is reported. The simulation of a switched reluctance motor drive with closed loop speed control is considered, and the results were validated by experimental tests executed on an industrial drive.<>
