Abstract
This paper extends works of linear controller reduction to nonlinear affine systems with the help of nonlinear balancing concept and technique. For stable controllers, nonlinear model reduction is directly applied to reduce the order. Discussion for unstable controller reduction focuses on the H(infinity) suboptimal output feedback controller and other controllers with observer-based structures. An unstable controller is reconstructed based on its left (right) coprime factorization such that the above controller reduction technique can be applied. Stability of the closed-loop system with a reduced controller is discussed and the upper bound of the closed-loop system performance with respect to L2-gain is also obtained. (Author)
