Method for operating an electric or fluidic actuator using a monitoring means for outputting a fault signal and movement controller for an actuator
A method for operating an electric or fluidic actuator, for which a setpoint position is predefined, includes the steps: provision of the setpoint position to a path planning unit and calculation of movement values from the setpoint position, provision of the movement values by the path planning unit to an open-loop control circuit and a closed-loop control circuit, calculation of a first manipulated variable component dependent on the movement values in the open-loop control circuit and calculation of a second manipulated variable component dependent on the movement values and on position signals of a position sensor assigned to the actuator in the closed-loop control circuit, combining of the first and the second manipulated variable component in an control unit and provision of a control signal resulting from the manipulated variable components to the actuator.
