Abstract
A method automatically detects stability of a regulator cascade having a number of cascaded regulators. A regulation error of a respective regulator is processed by the respective regulator and the processed regulation error is output as a regulator manipulated variable. A reference variable for the respectively downstream regulator in the regulator cascade is ascertained as a function of the regulator manipulated variable. The method includes: ascertaining an energy content of a respective regulation error; ascertaining whether an absolute value of a respective regulator manipulated variable exceeds an associated limiting value or not; and generating a stability measure for the regulator cascade as a function of the energy contents of the respective regulation errors and as a function of whether the respective regulator manipulated variables exceed their associated limiting values or not.
