Title:
気体圧アクチュエータ及びその制御方法
Document Type and Number:
Japanese Patent JP4629257
Kind Code:
B2
Abstract:
A controlling and computing device performs the steps of: differentiating a slider position represented by a position detection signal fed from a position sensor, and calculating the velocity of the slider, differentiating the calculated velocity so as to calculate an acceleration: using a slider target position, the slider position, the velocity and the acceleration to calculate position instruction values to be fed to two servo amplifiers; performing a computation on the respectively calculated position instruction values, so as to compensate for a pressure change which has occurred in each of pressure chambers due to a change in the position of a pressure receiving plate in a cylinder chamber; and producing the respectively compensated position instruction values to the two servo amplifiers.
