A semi-active design is developed to produce the desired reference control force by MR dampers. The structure used for numerical simulation is the base-isolated benchmark building. Seismic responses of the FPNS control, the simple displacement PNS control, the sample semi-active control and the optimal viscous damping control are compared under different seismic intensities. The effectiveness of each control case is evaluated based on the 'ideal isolation control principle'. The results show that the FPNS control can improve the isolation functionality for both low-to-moderate and extreme seismic intensities as well as enhance the isolation safety.
