Abstract
A method for controlling the movement of a component or machine element inhibited by friction, an adaptive pilot control being carried out, in which a variable pilot control value is applied to the manipulated variable to compensate for a friction influence, the change of the pilot control value being determined as a function of an actual value.
Claims12
A method for controlling a movement of a component or machine element inhibited by friction, comprising:
- carrying out an adaptive pilot control in which a variable pilot control value is applied to a manipulated variable to compensate for a friction influence, a change of the pilot control value being determined as a function of a control deviation, an absolute value of the pilot control value being decreased in the event of a sign change of a difference between the control deviation and a preset value;
- wherein a movement of a flap of an exhaust gas recirculating valve is regulated, the pilot control value being changed as a function of an actual position of the flap and an exhaust gas counter pressure.
A control unit, comprising:
- a control arrangement configured to control a movement of a component or machine element inhibited by friction by performing an adaptive pilot control in which a variable pilot control value is applied to a manipulated variable to compensate for a friction influence, a change of the pilot control value being determined as a function of a control deviation, an absolute value of the pilot control value being decreased in the event of a sign change of a difference between the control deviation and a preset value;
- wherein a movement of a flap of an exhaust gas recirculating valve is regulated, the pilot control value being changed as a function of an actual position of the flap and an exhaust gas counter pressure.
