    Abstract: A cylinder positioning system (1) comprising a control unit for a pneumatically driven cylinder (14) in a cylinder chamber is provided. The control unit comprising a controller configured to control a set of drive units of the cylinder positioning system. Each drive unit emits a drive current to a respective electromagnetic direct acting valve (9,10, 11, 12) of the cylinder positioning system. Each respective electromagnetic direct acting valve has a closing /opening time of less than 2 ms. The control unit is configured to receive a set position for the cylinder and an actual position for the cylinder, to compare the set position of the cylinder with the actual position of the cylinder and to emit control signals to the drive units to move the cylinder from the actual position towards the set position. By providing a very short time for actuation of the valves, in combination with an actual position for the cylinder a closed loop control can be achieved to control the flow to the actuating cylinder to be proportional over essentially the entire dynamic range of the pneumatic position control system. This in turn can make the control more accurate and robust and with smaller latency.

    Abstract: In accordance with the invention, a pneumatic load balancing system (1) comprising an actuating cylinder (14) for balancing a load (22) is provided. The pneumatic load balancing system comprises a pressure sensor (21) for determining the pressure in a chamber (16) of the actuating cylinder, and a controller (5) for controlling the air pressure in the chamber of the actuating cylinder via at least one air supply valve (9,10). The controller is configured to during a load balancing sequence continuously or periodically obtain a current air pressure in the chamber from the pressure sensor when supplying air to the chamber via said at least one air supply and to determine a balancing air pressure in the chamber when, if air fed to the chamber, the air pressure stops increasing or when the gradient of the pressure increase is below a pre-determined threshold value; or if the air pressure is let out from the chamber, the air pressure starts to decrease. The balancing air pressure thus determined is then used as the balancing air pressure for the actuating cylinder of the pneumatic load balancing system. Hereby an automatic setting of the air pressure required for load balancing can be achieved. The user does then not need to manually feed the required air-pressure and the system will use the correct air-pressure and mistakes in setting of the air pressure can be avoided.
