PURPOSE:To suppress vibrations by adding a vibration suppressing means to inhibit counting <=n pieces of increment and decrement signals if outputted alternately from a control value detecting means. CONSTITUTION:This control system comprises a controlled variable (position) detecting means 4', a speed counting means 51, a position counting means 52, a speed deviation detecting means 6', a speed deviation integrating means 7', a final deviation detecting means 8', a torque generating means 31 for a motor 30, etc. The continuous <=n pieces of both increment and decrement signals outputted from the means 4' are not counted and both signals following continues (n+1) pieces are counted as the 1-unit increment and decrement signals of speed. Thus it is possible to suppress the vibrations of such a system that tries to vibrate with the amplitude equivalent to the value of <=n pieces of output signals of the means 4'.
