Decentralized control of nonlinear large-scale systems using dynamic output feedback. (English) Zbl 0966.93015

Two systems are said to be similar if there exists a diffeomorphism which transforms the equation of one of them into the equation of the other one. The paper deals with a class of uncertain nonlinear large-scale systems comprising similar subsystems. A dynamic output feedback controller is designed via a Lyapunov function. The novelty here is that matched uncertainties are considered in the control design, and that by using a decomposition scheme, the known and uncertain interconnections are dealt with separately. The fact that the subsystems are similar reduces the computational complexity of the problem.
