A sensorless Single-Phase Induction Motor drive with a MRAC controller

This paper proposes a sensorless speed control scheme based on a model reference adaptive control (MRAC) and it is applied to a Single-Phase Induction Motor. The rotor speed control algorithm is based on robust model reference adaptive controller (RMRAC). The speed estimation technique is obtained from a MRAS (Model Reference Adaptive System) algorithm, based on the motor reactive power calculation. A compensated indirect rotor flux oriented control scheme witch include a asymmetry of the motor is used. Experimental results are obtained in DSP TMS320F2812 based platform and are presented for the validation of proposed scheme.
