摘要： A motor control system includes: a power supply; a converter; an inverter; an alternating-current motor; and a control unit that drives the motor in any one of sinusoidal PWM control, overmodulation control and rectangular wave control through operation control of the converter and the inverter. The control unit starts step-up operation of the converter when a current vector of motor current of the motor on a d-q coordinate plane becomes a current phase corresponding to motor torque, at which a system loss is equal between before and after starting the step-up operation, while the control unit supplies the direct-current voltage, supplied from the power supply, to the inverter without stepping up the direct-current voltage by the converter and performs the rectangular wave control of the motor in a state where the current phase is an optimal current phase.

摘要： A control device divides 360° corresponding to one cycle of a resolver angle into N zones, and determines whether or not a resolver angle θ in the current cycle exceeds a division border. When determined that resolver angle θ in the current cycle exceeds a division border, the control device calculates a time difference ΔT[n] between a calculation time T[n] in the immediately preceding resolver cycle and a calculation time T in the current cycle. The control device also calculates a resolver angle variation Δθ[n] with time difference ΔT[n] by adding 360° to the difference between resolver angle θ obtained in the current cycle and a resolver angle θ[n] obtained in the immediately preceding resolver cycle. The control device then calculates a rotation speed NM by multiplying, by a coefficient K, a value obtained by dividing Δθ[n] by ΔT[n].
