Patent Searching and Data


Title:
シリンダ位置決め制御方法
Document Type and Number:
Japanese Patent JP3626234
Kind Code:
B2
Abstract:
A cylinder positioning control apparatus designed to effect positioning of a cylinder by learning control that uses not only an overrun distance but also a cylinder speed as input data for control. The apparatus has a device for taking in a displacement x and speed V of a cylinder, a device for calculating a predicted overrun distance yi for the present drive from a predicted overrun distance yi-1 in the preceding drive, a cylinder speed Vi-1 at the time of outputting a braking signal during the preceding drive, and a speed Vi of the cylinder being driven, a device for judging whether or not a condition to be satisfied to output a braking signal is satisfied, and for outputting a braking signal when the condition is satisfied, a device for taking in a displacement xbp and speed Vbp of the cylinder when the braking signal is output, a device for taking in a displacement xstop of the cylinder when it has stopped, and a device for calculating a predicted overrun distance y1-1 and a cylinder speed Vi-1 at the time of outputting a braking signal, which are to be used in calculation for the subsequent drive, from the displacement xbp and speed Vbp of the cylinder when the braking signal was output, and the displacement xstop of the cylinder stopped.
