Abstract

In this paper, an improved discrete sliding mode control (SMC) is investigated for hypersonic vehicle (HV) cruise control system with packet dropouts. Packet dropouts are common faults in networked control systems (NCS), which occur in the sensor-controller and controller-actuator channels. A Lyapunov function is derived from the HV asynchronous dynamic model to design the state feedback. Set the HV system with state feedback as an augmentation system. A discrete SMC system is established for the augmentation system to improve the tracking performance and anti-fault robustness. We verify the discrete SMC approach in the cruising flight. A simulation example supports the theory.
