Abstract

PURPOSE: To establish the press-down control position less in phase difference between the reference value and the press-down position, by adding a unit correcting the value of press-down position reference.
CONSTITUTION: A differentiating unit 16 outputs the mobile speed of a press-down reference value ΔSa, and the mobile speed is limited to the mobile speed to which the press-down position ΔS can follow by a limiter 17. An integrator 18 integrates the differentiated output from the differentiating unit 16 via the limiter 17 to obtain the output ΔSb to a press-down control system 7. While the change rate of the reference value ΔSa is small, since the differentiation 16 of the reference value ΔSa does not reach the limit value of the limiter 17, the integration output ΔSb is integrated 18 as it is, and ΔSa and ΔSb are of the same waveform. Further, if the changing rate of ΔSa is great, since the output differentiating 16 the ΔSa is integrated 18 after it is limited with the limit value of the limiter 17, the changing rate of ΔSb is limited. But, even in this case, the phase of ΔSa and ΔSb is in agreement. Accordingly, the phase of ΔSb and ΔS can be in agreement.
