Abstract :
A method to calculate a region of attraction for controllers based on low-order block-oriented models is presented. The method uses a generalization of the circle criterion, which is less conservative than other input/output stability methods since the shape of the nonlinearity is also considered. The developed method is applied to a simulation example and additional applications are discussed
