A VARIABLE STRUCTURE ADAPTIVE POLE PLACEMENT CONTROL APPLIED TO THE SPEED CONTROL OF A THREE-PHASE INDUCTION MOTOR

Abstract Due to its flexibility in choosing the controller design methodology and the adaptive law (least squares, gradient, etc.), the Adaptive Pole Placement Control (APPC) is the most general type of adaptive control. It has been developed in an indirect approach and, as an advantage, it may be applied to non-minimum phase plants, because do not involve cancellation of plant zeros. The use of the variable structure systems theory has allowed to aggregate fast transient and robustness to parametric uncertainties and disturbances. In this paper, a Variable Structure Adaptive Pole Placement Control (VS-APPC) is applied to the speed control of an induction motor. Simulations and experimental results are shown.
