PMSM Drive Systems for Electric Active Steering (EAFS) Application: a Comparative Characterization

The aim of the study described by the present paper is to compare sinusoidal and trapezoidal permanent magnet synchronous machine (PMSM) drives technologies for electric active front steering. The design issues for the motors and explanatory finite elements analysis results are illustrated. The simulations of the control systems and power electronics have been ran and the results are presented and discussed. Prototypes have been built and tested. Experimental results, including comparative trapezoidal and sinusoidal control are presented and commented
