A microprocessor based prototype for electrical machines control using PWM modulation

This paper presents a prototype for electrical machines control using a microcomputer PC compatible using pulse width modulation (PWM). This prototype can be used to implement real-time digital control techniques for electrical machines in realistic situations. A PMCP16-200 board is used to interface the microcomputer with the proposed setup. Moreover, the use of a microcomputer simplifies control law and PWM techniques implementation since the supervisory software can be developed using the standard C language. Experimental results are presented to demonstrate the versatility of the proposed scheme when used to closed loop control of induction motors.
