A mechanical parameter estimation algorithm for permanent magnet synchronous motor (PMSM) drive systems based on sliding-mode observer is proposed in this paper. First, an extended sliding-mode mechanical parameter observer (ESMMPO) is presented to track system disturbances in real time, which inclu...
