Abstract: A motor control apparatus includes a direct-current power source and an inverter circuit, which includes a switching element. The motor control apparatus receives a current command value in every control cycle and calculates a current deviation accumulated value by accumulating the current deviation between the received current command value and the actual current value that flows through a coil of a motor. The motor control apparatus then computes a voltage command value in accordance with the current deviation accumulated value and controls the switching timing of the switching element based on the voltage command value. The motor control apparatus judges whether the computed voltage command value exceeds a range of the voltage that can be output from the inverter circuit and causes saturation. If it is judged that the voltage command value is saturated, the motor control apparatus restricts the accumulation of the current deviation.

Abstract: A controller for driving permanent magnet type synchronous motor. A motor terminal voltage or IPM (intelligent power module) input voltage necessary to achieve a target operating point is computed based on torque command and motor revolution. When the computed voltage exceeds an actual battery voltage, a booster is inserted between the battery and IPM, and the battery voltage, after being boosted, is applied between the direct current terminals of the IPM. Since the motor terminal voltage can be made so as to not exceed the boosted voltage even if the motor terminal voltage rises along with a rise in revolution and speed voltage, field weakening control becomes unnecessary.
