The vibration of high-rise tower structure requires active control. However，the problem of direct displacement observation and high-efficient low-dimension control strategy under single point needs to be solved. In this paper，a set of real-time continuous observation method of displacement from the inside of the tower is established by using modern video metrics technology，which provides the most direct displacement observer for the active control of the high tower. It avoids the tedious calculation process of building an acceleration observer，and then combining with the assumed external load to calculate the displacement after filtering. By using the equilibrium system space transformation and the equilibrium truncation method，a low-dimension controller is established with AMD at the top of the tower，which can effectively preserve the main dynamic characteristics of the structure. Taking a 700-meter-high tower under construction as an example，the active control simulation analysis under wind-induced vibration and earthquake is carried out. The results show that the control effect of the low-dimension controller with a few displacement states as feedback is basically the same as that of the full-dimension controller based on full state feedback，which can be used as an active control strategy for high tower structures.
