摘要： A pressure cylinder is connected to an air pressure source through a servo valve, the servo valve is controlled as an on/off switching valve by a control section in an advancing working step of a piston rod, and at the time of backward stroke of the piston rod, an operation position of the piston rod is detected by a position detector to feedback a detection signal to the control section, the servo valve is controlled by the control section such that a deviation between the operation position and a preset stopping position is eliminated, the piston rod is stopped at an intermediate stopping position, and a state in which substantially the same pressures are supplied to pressure chambers formed on opposite sides of the piston is maintained.

摘要： A positioning control system has a disturbance observer for estimating a disturbance from a displaced distance of a cylinder of a controlled object, and feeding back an estimated disturbance. The positioning control system also includes a saturation element and a low-pass element disposed in a feedback loop including the disturbance observer, and a saturated value changer for changing a saturated value of the saturation element based on a deviation. The saturation element is disposed in a forward path of a positive-feedback minor loop, whereas the low-pass element is disposed in a feedback path of the positive-feedback minor loop.

摘要： A method for controlling an air servo cylinder apparatus includes an advancing process of advancing a piston up to a target position by controlling, by a controller, servo valves individually connected to a pressure chamber on the head side and that on the rod side of the cylinder, and a pressurizing process of subsequently applying a required pressurizing force to the piston. In the advancing process, the piston starts to be driven with the servo valve on the head side opened to the air intake side and the servo valve on the rod side opened to the exhaust side. Thereafter, the opening degree of the servo valve on the rod side is varied into an opening degree in accordance with a deviation of the current position from the target position, and thereby the piston is smoothly decelerated as it approaches the target position.
