Abstract

A method for ascertaining measured values in a cyclically controlled system, the cyclic control having control time periods in which the system is controlled, and no-control time periods in which the system is not controlled, having the following operations of determining first integration time periods as a function of the cyclic control, the first integration time periods being situated within at least one of the control time periods, and/or determining second integration time periods as a function of the cyclic control, the second integration time period being situated within at least one of the no-control time periods; detecting one of the measured variables of the system dependent on the control; ascertaining summation and/or integration values by summation and/or integration of the measured variable during the first and/or second integration time periods; ascertaining the measured value for at least one of the control time periods and/or no-control time periods on the basis of time data of the first and/or second integration time periods and of the ascertained summation and/or integration values.
