© 2020 IEEE.Recently, finite control set-predictive torque control (FCS-PTC) is one of the most promising control methods for induction motor (IM) control due to its simplicity, fast dynamics, ability to handle nonlinearities, and the easy inclusion of constraints. However, time-varying parameters and unknown load input adversely affect its performance. Another consideration is the elimination of speed-sensor to reduce the maintenance requirements, hardware complexity, and cost. For this purpose, an adaptive fading extended Kalman filter observer is first designed for the estimations of stator flux, rotor mechanical speed, load torque, and stator resistance, and then this observer is included in the FCS-PTC based IM drive. Finally, a speed-sensorless FCS-PTC based IM drive is achieved, which rejects the disturbances caused by unknown input load and stator resistance variations.
