Multi-component force load cell calibration device

Provided are an output feedback frequency control device and a speed governor using the same. The output feedback frequency control device includes an integral control unit configured to generate an integral control signal by using a predetermined integral control constant (K) and an integral quantity of an angular velocity deviation (&#x394;&#x3c9;) of an external device, a differential control unit configured to generate a differential control signal by using a predetermined differential control constant (K), the angular velocity deviation (&#x394;&#x3c9;) of the external device, and the mechanical power (&#x394;P) of the external device, and a proportional control unit configured to generate a control input (u) for control of an operation speed of the external device by using the angular velocity deviation of the external device, the integral control signal generated by the integral control unit, the differential control signal generated by the differential control unit, and a predetermined control constant (R).
