By Aleksandar Zecevic, Dragoslav D. Siljak

Control of complicated structures: Structural Constraints and Uncertainty specializes in keep watch over layout below details constitution constraints, with a specific emphasis on large-scale structures. The complexity of such platforms poses severe computational demanding situations and critically restricts the categories of suggestions legislation that may be utilized in perform. This publication systematically addresses the most matters, and offers a few purposes that illustrate strength layout tools, so much which use Linear Matrix Inequalities (LMIs), that have turn into a well-liked layout instrument over the last twenty years. Authors Aleksandar I. Zecevic and Dragoslav D. Siljak use their years of expertise within the keep an eye on box to additionally:

  • Address the problems of large-scale structures as they relate to powerful regulate and linear matrix inequalities
  • Discuss a brand new method of making use of commonplace LMI strategies to large-scale platforms, combining graphic-theoretic decomposition strategies with acceptable low-rank numerical approximations and dramatically lowering the computational effort
  • Providing various examples and a large choice of purposes, starting from electrical strength structures and nonlinear circuits to mechanical difficulties and dynamic Boolean networks

Control of advanced platforms: Structural Constraints and Uncertainty will entice working towards engineers, researchers and scholars operating on top of things layout and different comparable components.
