This work proposes two vector control schemes for permanent magnet synchronous motors. They are destined to speed and position control, respectively, and are based on a control law called VS-RMRAC. Not being yet applied to the electric machines control, the VS-RMRAC control law presents robustness features that are potentially advantageous from the point of view of the closed loop PMSM dynamics. It also presents well established design and robust stability conditions, which makes its digital implementation easier. Both control structures are described and its respective design methods are presented. From simulation results, the behavior and performance of both structures are analyzed in face of load disturbances and parameter uncertainties. The speed control scheme and its simulation results are validated experimentally. This scheme is digitally implemented with fixed-point arithmetic using a TMS320F2812 DSP. Both schemes with its potentialities and limitations are then discussed.
