Abstract

PURPOSE:To improve accuracy of equivalent test, by heightening responding performance of absorption or driving torque to be generated by an electric motor at the time of start of acceleration or deceleration. CONSTITUTION:A control device for heightening excessive responding performance of an inertia compensation control is composed of a differentiator 20, a multiplier 21 and a compensation operator 22. Revolution of a driving shaft is differentiated by the differentiater 20 to detect speed of acceleration or deceleration. A forcing current calculating coefficient 23 is set and operated by the compensation operator 22. The speed of acceleration or deceleration is multiplied by the forcing current calculating coefficient 23 by the multiplier 21 to calculate a forcing current command value to be driven or absorbed by a DC motor 6. By adding this forcing current command value to an output of a constant current control operating amplifier 14, a constant torque control system whose responding performance is relatively low is compensated by a constant current control system of quick response.
