Event‐triggered output feedback control for two‐time‐scale systems with structured uncertainty

Abstract

SummaryThis paper investigates the event‐triggered output feedback control problem for the two‐time‐scale systems with structured uncertainty. Due to the non‐ignorable problem in applications such as equipment aging or parameter drifting, the robustness of the designed controller is worth discussing. A dynamic event‐triggered scheme is proposed to reduce the computational cost of the control signal. The results indicate that with the proposed event‐triggered controller, the system can achieve asymptotic stability without some common restrictions on the fast system rather than practical stability. Moreover, the Zeno behavior is excluded. Simulation examples with comparison studies illustrate the effectiveness of the proposed method.
