Outline of Final Research Achievements

This research proposed an optimal boundary control method based on numerical solutions for nonlinear distributed parameter systems. The method can use the non-linearity as an effective way to improve control performances without analytical solutions of the system. Firstly, we proposed the method for deriving a numerical control model from time responses by using dynamic mode decomposition, and the method of application of stable manifold method to the model. Secondly, we obtain facts on boundary controls from the Stokes-Dirac structure that gives the quivalent transformation between domain variations and boundary variations.
