Outline of Final Research Achievements

In this study, I have addressed a controller design for nonlinear systems with unmatched discontinuous uncertainty for two years. As the first step, a special case, in which the dynamics of an actuator is described by just an integral element, was considered. Although I planed to apply the controller design method based on a generalized Lyapunov stability theory for nonsmooth systems, and proposed a possible candidate for the problem, some mathematically unsolved issues have not been fixed yet. Because the proposed method successfully works under the problem statement in numerical simulations, the study is currently continued, aiming the research goal.
