| Abstract | ||
| In this paper vector control with variable frequency drive used to apply speed control of a three-phase AC Asynchronous and induction machines. The flux and torque references used to obtain the current components. Proportional-Integral controllers are used to keeping the measured current components at their reference values. The stator voltage references are the output of the PI current controllers. High-performance with the smooth operation is obtained using the proposed method. The differences can be seen in behavior dynamic state. When the motor is rotating at full speed with a full load,it reaches good current waveforms very easily due to the independent PI control of torque and magnitude of flux. In high and sudden variations of the reference input, the direct command is more efficient and less demanding for the equipment. The expressions of the fundamental variables (speed, torque, flux) and equivalent phase circuit of the machine will be reviewed. | ||
