| Outline of Final Research Achievements |
For sampled-data control and optimal control of a nonlinear system, new methodology is developed with numerical computational techniques and optimization techniques. First, in order to design a sampled-data controller for a nonlinear system with performance guarantee, it is proposed to discretize a given nonlinear system with an error bound and to design a robust controller. This is realized with the techniques of validated numerical computation and sum-of-squares polynomials. Also, for improvement of the stable-manifold method, which is a promising method for nonlinear optimal control, it is proposed to introduce the mean-vector-field method for trajectory computation of the associated Hamiltonian system and to develop a shooting method for systematic choice of an initial point of the trajectory. Moreover, application of nonlinear control and optimal control is considered to practical systems.
