  • Abstract ABSTRACT
    This thesis deals with the stabilization problem of uncertain large-scale systems with input delay and the time-delay interconnections. Due to the information transmission between subsystems, time delays are often encountered in large-scale systems and lead to the source of system instability. Some feasible and effective approaches to the control problem of the large-scale systems with time delays and uncertainties are provided in this thesis. First, the original nonlinear time-delay systems can be represented by the Takagi-Sugeno fuzzy model, which combines some simple local linear time-delay systems with their linguistic description. Then, two ways to synthesize the robust controller are developed as follows: (1) robust fuzzy compensatory controller, (2) fuzzy sliding mode controller. The adaptive fuzzy approach is proposed to approximate the upper bound of the uncertainties including the time-delay interconnections and the input delay. Based on the Lyapunov stability theorem, the proposed control schemes can guarantee the robust stability of the whole closed-loop system with input delay and time-delay interconnections. Finally, simulation results are given to demonstrate the validity of the two proposed controllers in this thesis.
