    • A control system for an electric three-phase variable speed motor includes an inverter for providing power to the motor and a control arrangement for controlling the inverter. The control arrangement includes a d and q axis currents determining module configured to repeatedly determine d and q axis currents based on detected currents of the motor. An MTPA control block repeatedly generates reference d and q axis currents based on the determined d and q axis currents and a ratio value such that the ratio of the reference d and q axis currents is equal to the ratio value, which is set to unity. A switching signal generation module repeatedly generates switching signals to control the inverter based on the reference d and q axis currents. A fine adjustment module calculates a magnitude of a current or power of the motor and determines an optimum compensation ratio value.

    • A motor control device according to the present invention includes a motor driving unit for driving a motor, a current vector controller, a magnetic-flux weakening current command generator, and one of a target command limiter and a q-axis current command limiter. The current vector controller controls a current of the motor by separating the current into a d-axis current and a q-axis current orthogonal to each other, in accordance with a target command value from the outside. The magnetic-flux weakening current command generator generates a d-axis current command to control the amount of the d-axis current, based on one of differences, i.e. a difference between a first predetermined reference value and the absolute value of a voltage command from the current vector controller to the motor driving unit and a difference between a second predetermined reference value and a q-axis component of the voltage command. The target command limiter sets a limit value of the target command value from the outside, based on an excessive amount of the d-axis current command over a negative upper limit.

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