In recent years, the adaptive cruise control (ACC) system has become widely adopted. The vehicle-positioning plays an important role in automotive platoon driving and can provide vehicle-position information through vehicle-to-vehicle communication. However, acquired often presents uncertainties given existence of variations traffic environment noise system. These uncertainties, turn, influence car-following performance a vehicle platoon. this study, we employ desired safety margin (DSM)...

Summary This article investigates the adaptive finite‐time control design with performance assurance for nonlinear Markov jumping systems. First, radial basis function neural networks are applied to tackle unknown terms. Subsequently, within framework of command‐filtered backstepping control, new error compensation signals devised remove effect caused by filter error. Additionally, an prescribed law event‐triggered mechanism is developed achieve a balance between tracking and bandwidth...

Scaling is one of the common problems in circulating cooling water systems, which can significantly affect efficiency equipment severe cases. At present, problem scaling usually controlled by adding treatment agents. However, taking external system synchronous condenser an ultra-high-voltage converter station as example, due to lack scientific understanding scale inhibitors, there often a excessive dosing, resulting unsatisfactory inhibition effects and difficulties wastewater discharge. In...

Car following is the most common phenomenon in single-lane traffic. However, propagation of small perturbation velocity leading car will affect traffic flow. Driving behaviors play an important role determination qualitative dynamics vehicles car-following process. Under different environments, driving depend on level perceived risk, acceleration and deceleration habits, reaction characteristics driver. The desired safety margin (DSM) model can directly describe process by using parameters...
