Adaptive Cruise Control Based on Model Predictive Control with Constraints Softening

Applied Sciences, 2020
In this paper, with the aim of meeting the requirements of car following, safety, comfort, and economy for adaptive cruise control (ACC) system, an ACC algorithm based on model predictive control (MPC) using constraints softening is proposed.

Trabecular bone ontogeny of the human talus

The Anatomical Record, EarlyView.
Abstract Studies of trabecular ontogeny may provide insight into the factors that drive healthy bone development. There is a growing understanding of how the juvenile skeleton responds to these influences; however, gaps in our knowledge remain. This study aims to identify ontogenetic trabecular patterns and regional changes during development within ...

Longitudinal Dynamic versus Kinematic Models for Car-Following Control Using Deep Reinforcement Learning

, 2019
The majority of current studies on autonomous vehicle control via deep reinforcement learning (DRL) utilize point-mass kinematic models, neglecting vehicle dynamics which includes acceleration delay and acceleration command dynamics.

Model Predictive Adaptive Cruise Control

2010 IEEE International Conference on Systems, Man and Cybernetics, 2010
In this paper, the Model Predictive Control (MPC) structure is used to solve the ACC problem and the performance of the design is tested using a realistic nonlinear vehicle model. A hierarchical control structure is used where MPC is placed on top of the hierarchy while the actuators are controlled by simpler linear controllers.

Graceful Degradation of Cooperative Adaptive Cruise Control [PDF]

IEEE Transactions on Intelligent Transportation Systems, 2015
Cooperative adaptive cruise control (CACC) employs wireless intervehicle communication, in addition to onboard sensors, to obtain string-stable vehicle-following behavior at small intervehicle distances. As a consequence, however, CACC is vulnerable to communication impairments such as latency and packet loss.

Does education policy affect teachers' learning needs? An international comparison of trends in teachers' continuing professional learning needs in secondary schools in Australia, England, Japan and the Netherlands

British Educational Research Journal, EarlyView.
Abstract Education policy changes are believed to influence teachers' continuing professional learning (CPL) needs, but there is limited empirical evidence to support these claims. This lack of deep understanding has significant practical implications. This study used a new circular conceptual framework to analyse teachers' CPL needs. Leveraging public

Adaptive Model Predictive Control for Cruise Control of High-Speed Trains with Time-Varying Parameters

Journal of Advanced Transportation, 2019
The cruise control of high-speed trains is challenging due to the presence of time-varying air resistance coefficients and control constrains. Because the resistance coefficients for high-speed trains are not accurately known and will change with the ...

Toward Carbon Accounting and Circular Harmony in Shipping Corporations: A Systematic Bibliometric Review

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines how carbon accounting can be used to govern, not merely report, circular economy principles in shipping corporations. Grounded in institutional theory and aligned with the UN 2030 Agenda, this study introduces circular harmony as an accounting design principle: Circular interventions are embedded in a single well‐to‐wake ...
