Abstract :
Closed-loop balanced truncation is a model reduction method that aims at preserving the closed-loop properties of the original controller. The authors show that this method is equivalent to frequency weighted balanced truncation with certain weightings, and how for observer-based controllers, a significant amount of computations can be saved because of the observer-state feedback structure of the controller
