Nonlinear Differential Flatness-Based Speed/Torque Control With State-Observers of Permanent Magnet Synchronous Motor Drives

Résumé

This paper presents a nonlinear control algorithm based on differential flatness approach for controlling a servo permanent magnet synchronous motor (PMSM) drive. The differential flatness approach is a model-based estimation. Subsequently, two state-observers are introduced to calculate a load torque disturbance and a stator resistance (representing losses in an inverter and motor) using its voltage drop. This can enable the improvement of the PMSM drive system and its efficiency. Using the flatness approach, we propose simple solutions to the dynamics and stabilization problems of the PMSM drive structure. In order to evaluate the proposed control algorithm, a hardware system is realized in a laboratory and digital estimation is obtained using a dSPACE controller DS1104 platform. Simulation and experimental results with a small-scale motor of 1000 W and 3000 r/min in a laboratory corroborate the excellent control scheme during motor-drive cycles.
