Control algorithms can be divided into open loop, feedback, feedforward, and combined feedback and feedforward control. Solutions proposed can be subdivided into (a) classical control, (b) optimal control, (c) robust control, (d) intelligent control, and (e) self-sustaining solutions and energy harvesting used in centralized and decentralized configurations. The most recent research on novel autonomous control systems intersects distributed control theory, agent-based modeling, bioinspired computational learning, and optimization algorithms.

The goal should be to achieve the best performance with minimum cost. A good number of papers have been published on the distribution of control devices in recent years. The purpose of this article is to present a review of the papers published on the placement of passive, semi-active, active, and hybrid devices for vibration control of structures subjected to various dynamic loading, such as earthquakes and winds. Significant additional research is needed, especially in the areas of semi-active and hybrid vibration control of large structures with hundreds or thousands of members, to make the adaptive/smart structure technology cost effective.

Vibration control of irregular highrise building structures using a recently developed tuned mass dampers (TMD), the bidirectional TMD (BTMD), is investigated. A key issue for effective implementation of a TMD is the determination of their tuning parameters. Eight different sets of equations for tuning the parameters of TMDs are investigated using a 5-story building with plan and elevation irregularity, and a 15-story and a 20-story building with plan irregularity subjected to seismic loading. Appropriate equations are recommended for building structures with a fundamental period of vibrations of greater than one second.

TMDs are divided into four categories: conventional TMDs, pendulum TMDs (PTMDs), bi-directional TMDs (BTMDs), and tuned liquid column dampers (TL-CDs).
