Thereby facsimile data can be transmitted so correctly to the receiver part so that the facsimile communication with use of radio SSB system can be successfully applied, although there may be an error between the transmitter frequency and the receiver frequency.

Abstract: An apparatus for controlling an adjustable-speed electric motor. The actual motor speed is sensed and compared with a commanded motor speed. A speed error signal, which depends on the difference between the actual and desired values of motor speed, is derived and applied to a proportional-plus-integral control circuit which converts it into a first torque command signal. The speed command signal is converted into a second torque command signal proportional to the rate of change of the speed command signal. The second torque command signal is added to the first torque command signal to provide a torque command signal. A control circuit responds to the torque command signal by controlling the operation of the motor in accordance with the torque command signal.
