Abstract: The present invention relates to a method for controlling a permanent magnet synchronous motor for maximizing use of voltage of a battery by voltage phase control within weak magnetic flux area and for achieving compensation for a torque error through a torque compensator when driving the permanent magnet synchronous motor for hybrid vehicles. In particular, when an interior permanent magnet synchronous motor mounted in a hybrid vehicle and an electric vehicle is driven in a weak magnetic flux area, the method controls the permanent magnet synchronous motor so that voltage use can be maximized in the weak magnetic flux area by using voltage near maximum voltage through a voltage phase control utilizing magnetic flux-based map data receiving a torque command and a motor speed/battery output voltage as inputs, and an torque error can be compensated using a torque compensation filter when a motor constant is changed in the weak magnetic flux area by a circumstance parameter.
