Abstract:
1. A method for controlling/regulating a physical variable of a physical system, in particular of a dynamic system, to a specific desired value/desired value profile using a pulse modulator by means of which a sequence of discrete modulation signals is generated, wherein said signals effect the control/regulation of the physical variable, characterized by the repeated execution of the following steps: a) determining an exact value or an approximation for the deviation between the momentary desired value and the momentary actual value of the physical variable, b) determining the respective change in the deviation which would result from the maintenance of the momentary modulation signal or the switching over to the other modulation signals, c) generating that modulation signal which results in the best approximation of the momentary desired value; and then d) applying said modulation signal to a resonator arranged to control/regulate said physical variable of said physical system.
