Nonlinear Model Reduction

Nonlinear model reduction in the general case is a challenge. The most popular method is Proper Orthogonal Decomposition. It can be generalized by means of empirical gramians. There is a generalization of balancing for a nonlinear model.An interesting new approach is trajectory piecewise model reduction. Links below will give you some introduction to these methods.
