Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a speed control system capable of improving the accuracy of speed control of a rotary travel cutting machine, a travel cutting machine and a sizing feed device, etc., the feed accuracy of position control, cut accuracy, and the form accuracy of a workpiece of a machine tool or the like. SOLUTION: The speed control system 10 is composed of a normative model setting instrument 11, an acceleration feedforward compensating means 12, a subtracted 13, a speed controller 14, an adder 15, an adder 16, an estimated load disturbance feedforward compensating means 18, and an inertia identification means 19.
