|Abstract ||:||In recent years, for progress of the semiconductor devices, synchronous motor is used for variable speed drive. However, the hunting often gives rise to speed fluctuation of the rotor. In this paper, the occurring conditions of hunting is investigated by Lyapunov's direct method, and the suppression control of the hunting is proposed. The all machine parameters and drive frequency affect the hunting. In these analysis, the physical aspect of hunting is derived from simulations.
The suppression control that bases on the physical aspect of the hunting is proposed.
The control method would suppress the hunting perfectly by controlling inverter output voltage.|
