Outline of Final Research Achievements

In this research, we consider developing a smart adaptive control system by expanding adaptive and/or data-driven control strategy. Especially, we developed novel model free control system design scheme based on the almost strictly positive real (ASPR) based adaptive output feedback control scheme, which has been well recognized as a practical control method with simple controller structure and robustness with respect to systems uncertainties and disturbances. Moreover, we tried to design robust control system for uncertain disturbances without disturbance model and achieved some positive results. With these results, we were able to investigate the realizability of the considered smart adaptive control system using data in present, past and future. In this research, we also tried to apply the proposed methods to experimental pilot systems and validated the effectiveness of the developed smart adaptive control.
