Adaptive output-feedback control of induction motors

Abstract

In this paper, we design an adaptive controller for the induction motor which ensures global asymptotic rotor velocity tracking performance and global exponential rotor¯ux tracking. In addition, the controller compensates for parametric uncertainty associated with the mechanical subsystem and only requires rotor velocity measurements. Experimental results are provided to illustrate the performance of the controller.

Current sensorless position–flux tracking controller for induction motor drives

“…Tracking of variable position and flux trajectories have not been considered in these papers. In [17], a current sensorless speed-flux tracking control is reported. An adaptation mechanism is added to estimate the parameters of the IM mechanical part.…”
