Passivity-Based Speed Control for Permanent Magnet Motors

This paper addresses the design, simulation and experimental validation of a Permanent-Magnet Synchronous Motor speed control. The control is based on the passivity strategy; special attention is paid on the stability control issue. SIMNON simulations illustrating the torque and speed response of the motor control are carried out to validate the control strategy. The algorithm control was programmed on a Texas Instruments TMS320F28335 Digital Signal Controller. Experimental results validating the control strategy are illustrated and analyzed.
