Controllers for linear interconnected dynamical systems with prespecified degree of stability

The approach of Anderson and Moore for the design of controllers for linear systems having a prespecified degree of stability is extended to the case of interconnected dynamical systems. The stability and performance of such controllers is studied when the system is subjected to structural perturbations as well as to loss of coordination information. For both the cases a stability condition is derived and bounds are developed for the performance loss. © 1979 Taylor & Francis Group, LLC.
