      Centralized, decentralized, and overlapping control designs for a segmented telescope 

      Li, K.; Kosmatopoulos, E. B.; Ioannou, Petros A.; Boussalis, Helen R. (IEEE, 1999)
      The accurate control of the segments of large segmented telescopes to achieve the desired shape could open the way for the construction of much larger telescopes with much better capabilities. In this article, we consider ...

      Decentralized indirect adaptive control of interconnected systems 

      Datta, Aniruddha; Ioannou, Petros A. (1991)
      Continuous time decentralized indirect adaptive controllers are proposed for a large‐scale system composed of N interconnected linear subsystems with unknown parameters. Each local adaptive law utilizes a normalizing signal ...
