Abstract :
This study presents a novel means of designing a simple and effective torque control for Permanent Magnet Synchronous Motor (PMSM). The overall stability of the system is shown using Lyapunov technique. The Lyapunov functions used contain a term penalizing incremental energy of control error, torque and stator flux, enhancing the stability. A new logical FPGA torque controller and flux observer based on Lyapunov theory are developed, analyzed and experimentally verified.
