ABSTRACT
This chapter provides a brief introduction to the full-scale implementations of passive, active, semi-active and hybrid control systems. It presents the theoretical investigation of the active control of adjacent buildings using hydraulic actuators as a potential full-scale implementation case. The chapter introduces the multi-objective hybrid control of high-tech equipment in a high-tech facility using both passive dampers and smart actuators to ensure the functionality of high-tech equipment against microvibration under normal working conditions and to protect high-tech equipment from damage when an earthquake occurs. Structural vibration control is one of the most important functions of a smart civil structure subjected to dynamic loadings such as strong winds and severe earthquakes. The full-scale implementations of passive energy dissipation systems for reducing structural vibration can be found in T. T. Soong and G. F. Dargush. The chapter also presents a general yet simple closed-form solution for actively controlled adjacent buildings linked by hydraulic actuators with linear quadratic Gaussian controllers under earthquake excitation.
