Dissipativity based anti-disturbance event-triggered tracking control of time-delay switched linear systems and its application to the conversion mode of XV-15 tilt-rotor aircraft

In this paper, a dissipativity-based tracking problem is studied for the time-delay switched linear system with disturbances. First, a composite disturbance observer is designed to estimate the nonlinear modeling disturbances and suppress the external disturbances with bounded energy. Then, to eliminate the adverse effects of time-delay on the system, the Lyapunov-Krasovskii functional is designed, and the feasible conditions related to the time-delay are established. In addition, the switch tracking controller is designed by combining the dissipation theory and the average dwell time technology. Furthermore, to reduce the quantity of signal transmission in the control process, an event-triggered control scheme is designed, and the trigger threshold function related to the tracking error is introduced, so that the trigger interval is adjusted with the tracking error. Using the Lyapunov theory and Jensen inequality method with low conservatism, a set of linear matrix inequality conditions are acquired. Finally, the simulation analysis of the conversion mode of XV-15 tilt-rotor aircraft shows that the proposed scheme is effective.
