Comparison between PI-DTC-SPWM and fuzzy logic for a sensorless asynchronous motor drive
asynchronous cage motors are among the most commonly requested machines accentuated by their extension to the field of electric vehicles. Therefore
the development of robust and sophisticated controls for this machine is of significant interest. Artificial intelligence control techniques
such as fuzzy logic
are at the forefront of recent research. However
their design becomes much more complicated for a motor via a multilevel inverter. The main purpose of this paper is to show that it is possible to achieve fuzzy logic control of a squirrel cage asynchronous motor supplied via the usual two-level inverter. This is achieved
by adopting a DTC strategy based on a sinusoidal PWM with multilevel inverter. It employs a feedback information estimator with dual structure between the sliding mode observer at low speed and the model reference adaptive system in sliding mode at high speed. For both installations
speed is regulated using a sliding mode controller.
