Abstract
A method and an apparatus for controlling system parameters, in particular for controlling the voltage applied to piezoelectric elements ( ) within a circuit (A) for charging and discharging piezoelectric elements ( ) are described. The method is characterized by modifying at least one control parameter for the control of a system parameter, in particular a target voltage for the voltage applied to a piezoelectric element ( ), in view of at least one systematic error occurring during a first control procedure of the system parameter to obtain a corrected control parameter for a second and/or a further control of the system parameter. The apparatus is particularly eligible for use with the inventive method.
