Sensorless Adaptive Backstepping Speed Control of Induction Motor
Proceedings of the 45th IEEE Conference on Decision and Control, 2006 This paper proposes an adaptive speed tracking control scheme for an induction motor subject to unknown load torque via backstepping analysis. The controller is developed under a special nonlinear coordinate transform such that speed control objective can be fulfilled.
