Adaptive partial state feedback control of the induction motor: elimination of rotor flux and rotor velocity measurements

In this paper, we present an adaptive, singularity free, partial-state feed back position tracking controller for the full-order, non-linear dynamic mo del of an induction motor driving a mechanical subsystem. The controller en sures global asymptotic rotor position tracking despite parametric uncertai nty associated with rotor resistance effects and the mechanical subsystem. In contrast to the previous work, the proposed controller requires only rot or position and stator current measurements (i.e. rotor velocity and rotor flux measurements are not required). Experimental results are provided to i llustrate the performance of the controller. Copyright (C) 2000 John Wiley & Sons, Ltd.
