In this project, we introduce a new current control method to reduce the electromagnetic torque ripple in AC induction motors. Our control strategy features hysteresis switching to accomplish the disturbance rejection task. We compare our results with the methods currently available in the literature both by compuer simulations and experiments. The testbed consists of an 1HP AC induction motor and electronic hardware ADMC401-ADVKIT from Analog Devices where the control algorithm is implemented. Our results show that out control strategy reduces the electromagnetic ripple up to 50% compared to currently existing methods.
