Title:
ACTUATOR DEVICE AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2017/195786
Kind Code:
A1
Abstract:
An actuator device (10) is provided with: a piston (21), which is housed in an internal space, and which forms, with a cylinder (20), a pair of pressure chambers (24, 25), said piston relatively moving with respect to the cylinder; a first actuator (30) connected to one of the pair of pressure chambers; a second actuator (40) connected to the other one of the pair of pressure chambers; a position detector (22) that detects the position of the piston with respect to the cylinder; a pressure detector (23) that detects pressure in one pressure chamber out of the pair of pressure chambers; and a controller (50) that controls the first actuator and the second actuator. The controller is configured so as to control one of the first actuator and the second actuator so that the position detected by the position detector is close to a target position, and to control the other one of the first actuator and the second actuator so that the pressure detected by the pressure detector is close to target pressure.
