| Research Abstract |
In this study, a simultaneous optimal design of a structural model for the semi-active control design and a model based semi-active control law has been studied. All semi-active control systems are essentially asymptotically stable because of the stability of general structural systems with structural damping and the energy dissipative nature of the semi-active control device itself. With the stability nature of semi-active control systems, parameters of the model for the control system design and those in the model-based semi-active control law were optimized simultaneously so that the closed-loop system with the detailed dynamic model that accurately approximates the dynamic behavior of the real structural system and the semi-active control law obtained with the model for the control system design without considering the modeling error. The genetic algorithm was adopted to the optimization. The effectiveness of the present approach was shown with simulation studies.
