Abstract EN
This paper considers the problem of H∞ output tracking control for discrete-time switched systems with time-varying delay and external disturbances.
The control scheme combining disturbance observer-based control (DOBC) and H∞ control is proposed.
The disturbances are assumed to include two parts.
One part is generated by an exogenous system, which imposes on system with control inputs in the same channel.
The other part is supposed to have the bounded H2 norm.
A new disturbance observer is developed to estimate and reject the first case disturbances for switched system with time-varying delay, and the second case disturbances are attenuated by H∞ control scheme.
The stability analysis of the closed-loop system is developed by switched Lyapunov function, and a solvable delay-dependent sufficient condition is presented in terms of linear matrix inequalities (LMIs) and cone complement linearization (CCL) methods.
A numerical example is given to demonstrate the effectiveness of the proposed composite control scheme.
