Abstract:
A control system comprising:a measurement system for generating a first and a second position signal, which position signals are a measure of an instantaneous value of the position of a second part of a driving system, which second part is to be positioned with respect to a first part of the driving system;error signal generating means for generating an error signal in response to a reference signal and the first and a second position signal, which reference signal is a measure of a desired value of the position, which error signal is a measure of the difference between the desired value and the instantaneous value of the position, which the error signal generating means derive weighting factors from the reference signal, for weighting the position signals with the weighting factors, and for determining a sum of the weighted position signals;energizing means for energizing the motor in dependence on the error signal.
