Sensorless Predictive Control for PMSM Using MRAS Observer

This article presents a sensorless MPC (Model Predictive Control) for a PMSM (Permanent Magnet Synchronous Motor) in which the rotor speed is provided by a MRAS (Model Reference Adaptive System) observer, and general control strategy is FOC (Field Oriented Control) type. The results of the numerical simulations show the superiority of the MPC control system compared to the FOC type control system in the case of parameter variation and rapidly varying torque load with a random component. The relatively low complexity of the number of arithmetic operations required to implement the estimation and control algorithms recommends the implementation of an embedded system in real time in future works.
