Energy Market-Based Control of Linear Civil Structures

Structural control systems are used to limit structural responses during large external loads such as winds and earthquakes. The semi-active control approach has grown in popularity due to inexpensive control devices that consume little power. Structural control systems of the future will likely be large-scale systems defined by high actuation densities. Decentralized control approaches can be used to control large-scale systems that are too complex for a traditional centralized approach. This paper describes the derivation of a decentralized energy marketbased control (EMBC) approach that models the structural control system as a marketplace. The interaction of free-market buyers and sellers results in an optimal allocation of limited control system resources. A 20-story structure is selected as an illustrative example to compare the performance of the EMBC and the centralized linear quadratic regulation (LQR) approaches.
