PURPOSE:To obtain a stable and equal response even if the inertial moment of a drive system varies by correcting a gain in response to the variation in the inertial moment of the system. CONSTITUTION:A mechanical constant stored in advance in a memory 7 is led to a correcting gain calculator 8 in response to a signal from a coupling variation pattern detector 6 for detecting the coupled state of the first and second couplers 3a, 3b. The calculator 8 corrects the gain of a speed deviation signal in response to the constant output from the memory 7, and leads the signal corrected in the gain to a speed controller 11. The controller 11 controls a thyristor converter 5 which supplies the armature current of a DC motor 1 so that the speed deviation signal corrected in the gain becomes zero while compensating the variation in the power source current. |
