The permanent magnet-assisted synchronous reluctance motors (PMa-SynRM) have nowadays emerged as an attractive alternative for high performance variable speed drive applications. This paper investigates the dynamic performances of a PMa-SynRM drive using the maximum torque per ampere (MTPA) control strategy. A hysteresis controller and a PI controller have been used in the inner current and outer speed control loops, respectively for the structural realization of the cascaded control system of the PMa-SynRM drive. In order to realize a high performance PMa-SynRM drive, the damping factor has explicitly been specified in the design of the speed PI controller gains making use of the pole-placement interpretation of the symmetric optimum method. The efficacy of the proposed control system incorporating the tuned PI controller gains has been confirmed via offline simulation using MATLAB/Simulink. The dynamic performances of the proposed PMa-SynRM drive have also been evaluated using Typhoon HIL604 real-time emulator for experimental validation of the offline simulation results.
