Design of Decentralized Block Backstepping Controllers for Large-Scale Systems to Achieve Asymptotic Stability

Based on the Lyapunov stability theorem, a design methodology of adaptive
block backstepping decentralized controller is proposed in this thesis for a class
of large-scale systems with interconnections to solve regulation problems. Each
subsystem contains m blocks¡¦ state variables, and m- 1 virtual input controllers
are designed from the first block to the (m - 1)th block. Then the proposed
robust controller is designed in accordance with the last block. Some adaptive
mechanisms are embedded in the backstepping controllers as well as virtual input
controllers in each subsystem, so that the upper bounds of interconnections
as well as perturbations are not required. Furthermore, the dynamic equations
of each subsystem do not need to strictly satisfy the block strict feedback form,
and the resultant controlled system can achieve asymptotic stability. Finally, a
numerical and a practical examples are given for demonstrating the feasibility of
the proposed control scheme.
