Abstract :
An efficiency optimization method for vector-controlled surface permanent magnet synchronous motor (SPMSM) drives including online estimation of all parameters is presented. The controllable electrical loss can be minimized by the optimal control of the armature current vector. Parameter variations except at near the nominal conditions have undesirable effect on the controller performance, so it is essential to estimate motor parameters. A stability study based on the second method of Lyapunov guarantees the stability and convergence of the estimated parameters under certain conditions. The simulation results show the feasibility and desirable performance of the proposed controller and observer
