Zusammenfassung:	In order to control the peripheral speed of a rotating object, such as a grinding wheel, the current of the motor driving the grinding wheel is periodically integrated during a deceleration and an acceleration to obtain a composite signal from the integrator which reflects the necessary change in speed due to the decrease in diameter of the grinding wheel, which correction signal is combined with a signal representing a control input for a maximum size and supplied to the controller for the grinding wheel motor.
