Abstract:
1. A method for moving an element based on movement of at least a primary actuator which is adapted to receive a flow of a primary fluid, the method comprising: providing a desired movement of the element, simultaneously providing at least three shares of the flow of the primary fluid by at least three independently operating fluid providers, each fluid provider comprising a separate controller and a fluid supply, the controller controlling operation of the fluid supply, each share having a flow rate and a pressure defining power by which the share can move an object, operating the actuator by use of the power from the at least three independently operating fluid providers, sensing an actual movement of the element, and moving the element as a consequence of the operation of the actuator, wherein each controller controls the associated fluid supply to provide the share of the primary fluid to the at least one primary actuator based on the desired movement of the element and the actual movement of the element without considering the power provided by the other fluid providers until the desired movement is obtained.
