As physical obstacles, vehicles have significant impacts on the efficient propagations of safety-related information in vehicular ad hoc networks (VANETs) by frequently obstructing the LOS links between transmitters and receivers. Obstructing effect will diminish the effective coverage of safety-related information and incur severe impact on road safety. However, this impact has not been addressed effectively. In this paper, we first present the definition of broadcast efficiency as the metric for quantizing the obstructing effect. We investigate the optimization issue for mitigating the impact of obstructing effect on the propagation of safety-related information and propose a graph theory-based optimization algorithm. For a distributed implementation of this optimization in VANETs, we further propose the maximum broadcast efficiency relaying (MBER) algorithm. MBER maximizes the effective coverage of information, meanwhile, meets delay and reliability constraints by incorporating broadcast efficiency and propagation distance in relay contention. Simulation results demonstrate that MBER promotes the effective coverage of safety-related information in VANETs with varying vehicular distribution. © 1967-2012 IEEE.

This paper focuses on the robust semi-global coordinated tracking of general linear systems subject to input saturation together with input additive disturbance and dead zone. A fully distributed algorithm which relating only with the number of the following agents and the relative state information of its neighbors is first constructed, and then sufficient conditions guaranteeing the robust semi-global consensus tracking and the robust semi-global swarm tracking are provided, respectively, on the basis of the low-and-high feedback technique. Finally, numerical simulations are performed to illustrate the effectiveness of the theoretical results. © 2017

As one of the most basic behaviors of vehicles in the intelligent transportation system, the lane changing in highway environment influences the safety and efficiency of driving. As a result, it has always been paid much attention by researchers. In the process of the lane changing, it is necessary to consider the kinematic constraints and optimization of safety and rapidity. The existed geometrical methods mainly use curves to fit the path without considering the kinematic constraints of the vehicle. In this paper, we study and design the overall frame of generating the path for lane changing using model predictive control. Model predictive control shows its advantage in solving multi-constraint optimization and predicting the future states. Therefore it is used to optimize the rapidity and smoothness of the lane changing process. Software simulation proves that the trajectory planned by the model predictive control has better smoothness than the trajectory planned by the geometrical method. Finally, a lane changing experiment is conducted on the micro vehicle-based hardware simulation platform. The experimental result further verifies the feasibility of the proposed path planning method.

Aiming at the current situation of poor quality of artificial intelligence teaching and weak students' interest in learning, a case teaching method is proposed. This paper analyzes the teaching status of artificial intelligence firstly, and then systematically describes the case teaching method. Finally, the necessity of introducing case teaching method into artificial intelligence teaching is studied. Practice shows that the case teaching method can effectively enhance students' self-learning ability, improve students' comprehensive innovation ability, and promote the development of artificial intelligence teaching.

In recent years, structural controllability of complex network has aroused great interest. In literatures fruitful results have been achieved on finding the minimum number of driver nodes which guarantee the network structurally *** for selecting a group of such driver nodes are also proposed. However, for practical applications, it is always desirable to have more possibilities for driver nodes selection such that additional requirements caused by network operation or control can be considered. This paper focuses on finding complete schemes of eliminating redundant driver nodes from a given available driver node set without destroying the structural controllability. We solve this problem according to the two algebraic conditions of structural controllability respectively and the effectiveness and efficiency of the algorithm are also discussed based on some related tests.

In view of the rapid development of contemporary computer technology, the problems that can be solved by computer technology are more and more complicated. Therefore, it is required that contemporary college students need to master certain computer operation skills and basic application skills of computer software combined with their professional knowledge before they officially enter the society. In this context, aiming at the computer-based teaching mode of non-computer majors in colleges and universities, the author analyzes the current situation of computer basic teaching in colleges and universities through his many years of teaching experience, and discusses the shortcomings in the development of computer courses in colleges and universities. Based on the degree of social requirements for contemporary college students to master computer technology, how to make university computer teaching cater to the continuous development and progress of computer science and technology, combined with the future computer skills of undergraduate students, the author puts forward some computer teaching reform opinions.

In this paper, we propose a cooperative motion planning method for a group of connected and automated vehicles (CAVs) crossing a lane-free intersection without using explicit traffic signaling. This multi-vehicle motion planning task is formulated as a centralized optimal control problem. However, the solution to this optimal control problem is numerically intractable due to the high dimensionality of the collision-avoidance constraints and the nonlinearity of the vehicle kinematics. A two-stage strategy is proposed for generating online solutions: at Stage 1, the CAVs are requested to reach a standard formation before entering the intersection;at Stage 2, the vehicles cross the intersection. As the motion planning sub-problem at Stage 2 begins with a standard configuration, the optimal solution to this standard sub-problem can be computed offline in advance and applied online directly. On the other hand, the formation reconfiguration sub-problem at Stage 1 is easy to solve online. Through dividing the entire dynamic process into two periods, the difficulties in the original optimal control problem are significantly reduced so that the real-time performance is achieved. © 2018 IEEE.

A new type of exponential rate is proposed, in order to improve the dynamic quality of servo motor speed control system. The reaching law relates the approach speed to the change of the system state quantity, which overcomes the shortcomings of the conventional exponential approach rate. The inherent buffeting problem of the sliding mode is effectively suppressed. The reaching law is applied to the servo motor speed control system, and a sliding mode variable structure speed controller based on a novel exponential reaching law is designed to replace the traditional PI regulator. Simulations and experiments show that the speed controller is robust to system parameters uncertainties, external disturbances and noise, and it can effectively improve the dynamic and static characteristics of the system. This makes the servo motor can be better applied to the robot servo system.
