Abstract
This paper focuses on the consensus problem of a vehicle platoon system with time-varying topology via self-triggered control. Unlike traditional control methods, a more secure event-triggered controller considering the safe distance was designed for the vehicle platoon system. Then, a Lyapunov function was designed to prove the stability of the platoon system. Furthermore, based on the new event-triggered function, a more energy efficient self-triggered control strategy was designed by using the Taylor formula. The new self-triggered control strategy can directly calculate the next trigger according to the state information of the last trigger. It avoids continuous calculation and measurement of vehicles. Finally, the effectiveness of the proposed two self-triggered control strategies were verified by numerical simulation experiments.
Highlights
In recent years, multi-agent systems have been widely applied in intelligent transportation (Hee Lee et al, 2013; Vilarinho et al, 2016)
Based on the above considerations, we studied the consistency of time-varying topology for vehicle platoon system with secondorder dynamics by using distributed event-triggered control and self-triggered control strategies
In order to improve this problem, we apply the self-triggered control strategy to solve the problem of intelligent vehicle formation
Summary
Multi-agent systems have been widely applied in intelligent transportation (Hee Lee et al, 2013; Vilarinho et al, 2016). In order to obtain the trigger moment, we need to constantly obtain the state information of surrounding vehicles and calculate whether the trigger conditions are met in the distributed event-triggered control function It is because of continuous communication and computation that an eventtriggered control strategy cannot reduce the detection loss in essence. Authors designed a self-triggered control strategy for the second-order multi-agent system with fixed topology to ensure the consistency of the formation system (De Persis and Frasca, 2013). Based on the above considerations, we studied the consistency of time-varying topology for vehicle platoon system with secondorder dynamics by using distributed event-triggered control and self-triggered control strategies.
