Abstract
PURPOSE:To reduce a stationary error in the time of heavy load together with improvement of stability in the time of light load by enhancing a gain of the system in the time of light load. CONSTITUTION:The weight of the load 14 including a generator driven by a motor 13 is detected by two elements of a torque meter 16 and a tachogenerator 15. These two elements, torque and speed are multiplied by a multiplier 18, and the full output of the motor 13 is detected by the multiplier 18. While, a comparison section 17 outputs the deviation between a desired value of speed and full speed of the motor 13 to a multiplication section 19. A signal for the detected weight of full load 14 is outputted to the multiplication section 19 from the multiplier 18, and it is decided so that a gain of the system decreases when the weight of the load 14 is light and so that a gain of the system increases when the weight of the load 14 is heavy. Accordingly, stationary error, response efficiency and stability against load variation are improved.
