ABSTRACT
The chapter overviews the past and present results pertaining to the area of decentralized control of large-scale systems. An emphasis is laid on decentralization, decomposition, and robustness. These methodologies serve as effective tools to overcome specific difficulties arising in large-scale complex systems such as high dimensionality, information structure constraints, uncertainty, and delays. The overview is focused on recent decomposition approaches in interconnected dynamic systems due to their potential in providing the extension of decentralized control into networked control systems, switching systems, and dynamic systems with abrupt-change parameters.
