    • A conventional apparatus with the above operation, includes a torque ripple due to harmonic wave components included in the detected fundamental wave of current frequency of the detected apparatus for controlling rotation speed, switching dead time and the like and accordingly, harmonic wave components are included in the induced voltage. Therefore, a ripple is generated in an estimated-calculated rotation speed and accordingly, precise speed control was not possible. Also, it was difficult to handle the apparatus by using an encoder and hole-sensor of the rotor position detection unit. To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, there is provided an apparatus for controlling rotation speed of a synchronous reluctance motor, including a position estimation unit for controlling rotation speed of the synchronous reluctance motor by estimating the flux angle of the rotor and rotation speed of the rotor according to the low speed or high speed region, and the apparatus can control the motor in the high speed area or low speed area, stabilize the transient state generated in the process that the motor is converted from the low speed area to the high speed area and show stable speed control performance, thus to perform more precise speed control.
