Abstract:
1. A position control method for an axle, comprising: predefining a reference value and a position value for a position controller; predefining a reference value change and a temporal offset between respectively immediately successive reference values for the position controller; determining future reference values by the position controller, wherein the position controller uses the reference value, the reference value change and the temporal offset; determining the corresponding setpoint position values by the position controller, wherein the position controller uses the reference values; determining a manipulated variable and for a future setpoint position value an expected manipulated variable and an expected position value respectively by the position controller, wherein the position controller uses a model of the axle, and wherein an overall deviation of the position value and the expected position value from the corresponding setpoint position value is optimized according to a predetermined evaluation function; and actuating the axle according to the manipulated variable by the position controller.
