Hydraulic operating cylinder or actuator control method for actuating e.g. gas shuttle valve, involves calculating control parameter based on target value, operating and gas force parameters and outputting control parameter

摘要

The method involves determining operating parameters and a parameter that specifies gas force acting on a piston (1) and/or on a gas shuttle valve during stroke movement. A control parameter is calculated based on a target value of a control factor and the operating and gas force parameters using a variable transfer function. The control parameter is outputted to an output unit for activating a corresponding control signal. Independent claims are also included for the following: (A) a computer program for controlling a hydraulic actuator (B) a controlling device for controlling a hydraulic actuator.
