Abstract: This paper explores the possibility of using hybrid control platform to mitigate the vertical microvibration of a batch of sensitive equipments installed in high technology building subjected to nearby road vehicle-induced ground motion. Two-dimensional dynamic equation of motion of a typical three-story high technology building is established by using finite element method. Hybrid control system composed of passive mounts and active hydraulic actuators is then constructed with sub-optimal control algorithm based on the finite element model of the building structure. The simulation results show that the performance of hybrid control platform is superior to that of passive control platform because of the higher performance and robustness.
