Comparison of Sensorless Control Strategies for AC Induction Motor
Václavek Pavel, prof. Ing., Ph.D.
The aim of this paper is to compare high performance field oriented sensorless control strategies for AC induction motor. Classical vector control, direct torque control and sliding mode control are discussed herein. The comparison is carried out from different aspects. The first part is interested in precision determination of the control algorithms by the simulations in Simulink environment. The second one consists in algorithmic complexity measurement. It is provided using Performance tools from Simulink, namely with Profiler. It gives time requirements of principal parts of control algorithms. Both control schemes use the same flux and speed observer that works well also in low speed range. The G-model of AC induction motor is employed in simulations.
