Abstract
A control apparatus of a synchronous reluctance motor includes a torque current correction unit (16) that generates a torque current command tracing a load torque so as to make the output torque of the motor coincide with the load torque. The control apparatus may further include a position and speed estimation unit (13) that estimates the position and speed based on three phase voltage equation to improve control performance in a voltage saturation state.
