Abstract
Active structural-control is a new technology of earthquake resistance strategy for civil structures. This technology, however, is currently under way of development, having some issues to be solved. One of the most significant issues is how to control buildings regardless of earthquake severeness. This paper presents variable gain-based structural control accounting for AMD stroke limitation. The control algorithm is based on the philosophy of Maximal admissible set of initial state, which was originally proposed for a system with no input excitation. Simulated and experimental results demonstrates how effectively and satisfactorily the presented methodology works.
