MICROPROCESSOR CONTROLTECHNIQUES AND MODELLING OF ADJUSTABLE SPEED DRIVES

摘要

This paper presents microprocessor control techniques for variable speed drive models. The paper gives results of simulations studies of the dynamic behaviour of a variable speed drive model using the symmetric and asymmetric PWM methods and explains why these techniques are superior than the traditional PWM method. Validation was taken by comparing the above results, with results taken from laboratory tests as were addressed in the reference literature.
