Title:
ACTUATOR DEVICE AND CONTROL METHOD
Document Type and Number:
Japanese Patent JP2017203504
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an actuator device capable of locating with high accuracy.SOLUTION: An actuator device 10 comprises: a piston 21 accommodated in an interior space to form a pair of pressure chambers 24 and 25 together with a cylinder 20 and move relative to the cylinder; a first actuator 30 connected to one of the pair of pressure chambers; a second actuator 40 connected to the other of the pair of pressure chambers; a position sensor 22 for detecting the position of the piston with respect to the cylinder; a pressure detector 23 for detecting the pressure in any one pressure chamber of the pair of pressure chambers; and a controller 50 for controlling the first actuator and the second actuator. The controller is configured to control one of the first actuator and the second actuator so that the position detected by the position sensor comes closer to a target position; and to control the other of the first actuator and the second actuator so that the pressure detected by the pressure detector comes closer to a target pressure.SELECTED DRAWING: Figure 1
