The device has an error detector for an error in the respective certain parameter, and for derivation of a corresponding error signal. It has a feed-back circuit with a closed control circuit containing the error detector. When an error signal appears, it minimises the error in the certain parameter. The device has a forward control circuit (5, 8, 11) with open loop and a parameter setting circuit (8) which responds to the error signal and reduces the certain parameter error accordingly. |
