A great deal of studies are recently pursued to mitigate seismic responses of structures through active control arrangements. It may be necessary for response control systems to provide state estimators or structural identifiers when dynamic characteristics are tentatively varied or phisical properties are somewhat uncertain in objective control plants.The present study is concerned with model reference adaptive control systems to try for the response mitigation of structural constructions having unknown properties, wanting state informations and accepting plural control forces. State variable filters are prepared to compensate for lack of manipulation signals, which are divided into model segments and set in pole assignment way to reduce the increment of auxiliary state variables.Numerical works are carried out to confirm the validity of the manipulation algorithm and the performance of the control systems under typical quake excitations.
