A simplified vector control is proposed as a driving method of permanent magnet synchronous motor (PMSM) for electrical household appliances. Control structure is simplified by eliminating the speed regulator and the current regulator from the conventional vector controller. Output voltage references are determined by feedforward-like calculation using motor parameters, rotation speed command, and current references. In the static characteristic, the proposed vector control method is almost equal to the conventional one, because the voltage references are calculated in the vector space. A practical estimate equation of rotor position is proposed, and the phase locked loop control approach is employed to drive PMSM without position and speed sensors. Design method of two control gains is given. Finally, the effectiveness of the proposed control is verified by simulation and experiments.
