Abstract :
This paper describes an integrated methodology for determining a decentralized control structure for LSS with corresponding low-order controllers. Structural decomposition is based on the use of the Generalized Hessenberg Representation (GHR). Controller design is accomplished by utilizing frequency weighting in the performance criterion, together with projective controls. The methodology is illustrated by a case study of a 40th-order space structure model.
