1. A method for generating a control command to at least one actuator of an electrohydraulic machine, comprising the steps of:
receiving and monitoring an input signal provided by a user interface, the user interface being a multi-axis joystick;
determining if the monitored input signal is related to a user-induced input or a non-user-induced input;
generating the control command upon processing the input signal in dependence on whether the input signal is a user-induced input or a non-user-induced input,
wherein the step of determining the non-user-induced input is performed by detecting an oscillating movement of the joystick along an axis of the multi-axis due to a non-user-induced input, determining whether the input signal crosses a first predetermined threshold located on a first side of the axis and a second predetermined threshold located on a second side of the axis a predetermined number of times in a predetermined time period, the first side of the axis and the second side of the axis are separated by a zero position of the user interface.
