Sampled-data internet of connected vehicles control with channel fading and time-varying delay

Abstract

Abstract This paper is concerned with sampled-data internet of connected vehicles (IOCV) control systems with a communication channel fading and time-varying delay. A hybrid IOCV system model is established, where the communication channel fading and time-varying delay are given full considerations. Based on the model, by employing Lyapunov-Krosovskii functional, a new sampled-data controller method with variable sampling period is derived, which can robustly stabilize the IOCV system with a given level of disturbance attenuation. Furthermore, the obtained sampled-data controller is complemented by additional conditions established to guaranteeing string stability and zero steady state tracking errors. Finally, the effectiveness and superiority of the proposed control strategies are verified by both numerical simulation and experiment with four-laboratory scale cars.
