Abstract

In this work a general decentralized control approach is presented for large flexible structures. The structure is decomposed into substructures for which the linear quadratic regulator theory is used to determine the decentralized controllers at substructure level (subcontrollers). The reaction forces at the substructure boundaries are balanced by the control forces generated within the substructures. The subcontroller of each substructure is then used to assemble the controller for the whole structure. The computational effort required in the approach is substantially less compared with the complete structural model.
