| Outline of Final Research Achievements |
We have conducted research on closed-loop system identification, in which a mathematical model of a dynamic system that exists in a closed-loop environment with uncertain information about the controller and external signals is constructed from only the input-output data of the system. We proposed a new framework for system identification that enables identification under uncertain controller information regardless of whether the target system is stable or unstable, linear or nonlinear, and demonstrated its effectiveness through detailed numerical examples. When the target dynamical system is linear, we proposed a method that can systematically determine the model order. In the case of a linear scalar system, it is shown that a continuous-time system model can be constructed with high accuracy even when there is no controller information at all.
