Dual‐terminal event‐triggered dynamic output feedback H∞ control for aero engine networked control systems with quantization

Abstract

AbstractThis study deals with the problem of dual‐terminal event‐triggered dynamic output feedback (DOF) control for aero engine networked control systems (NCSs) subject to network‐induced delay, external disturbance, and quantization effects. First, we established a generalized mathematical model of the aero engine. Second, a dual‐terminal dynamic event‐triggered mechanism (DETM) was designed to reduce the utilization of the network bandwidth. In addition, a DOF controller with a compensation function was proposed to stabilize the system. By utilizing the Lyapunov‐Krasovskii (LK) method, the stability criteria were determined. Accordingly, the design conditions of the DOF controller and DETMs were presented. Furthermore, based on a genetic algorithm (GA), a parameter tuning method was proposed to obtain the allowable delay upper bound with less conservatism. Finally, some examples were presented to show the effectiveness and superiority of the presented scheme.
