ABSTRACT
In this paper, a new nonlinear robust adaptive decentralized control for a class of
large-scale interconnected system (LS-Inter-SYS) with the uncertain parameters and
disturbances is proposed. By using the mean-value theorem of the multivariate function, the
cross terms and the uncertain parts of the LS-Inter-SYS are extended to the new state
variables and adaptive tracking estimated, then the LS-Inter-SYS can be divided into
separated subsystems. Simulation results show that the new decentralized robust adaptive
control method is effective and has the characteristics of universality, simplicity and rapidity
by introducing the K-Class functions and additional control variable.
