Center Manifold Reduction of Nonlinear Dynamics With External Periodic Excitations

In this new article, we present a straightforward approach to accomplish model order reduction on the invariant center manifold for large-dimensional nonlinear systems subjected to external periodic excitations. This relatively plain and direct approach is applicable to both parametrically excited and constant coefficient nonlinear systems. Our approach is powerful because it is liberated from typical […]

Simplifying Nonlinear Systems With External Periodic Excitation

In my latest article, we present a powerful direct approach to simplify complexly structured nonlinear systems with external periodic excitation via normal forms. This approach is liberated from special treatment of nonlinear systems such as ‘book-keeping’ parameters, detuning parameters etc. It does not mandate the system to be minimally excited and the system may possess […]
