摘要
在V2X(vehicle to everything)智能网联环境中,新能源货车的调度系统需获取实时的动态信息。利用传统的粒子群调度方法,系统存在易陷入局部最优和求解效率不高的问题。在研究新能源货车多目标优化问题的基础上,提出改进的新能源货车粒子群调度方法。改进惯性权重更新方式使惯性权重呈非线性递减,降低系统陷入局部最优的风险;设计“先验性”路径编码的方式,优化路径编码,提高算法的求解效率,减少新能源货车的能源消耗。仿真结果表明:总路径长度、路径平滑度和算法的收敛速度方面均有改善,在静态和动态环境中,改进的方法均能实现新能源货车的合理调度,对于构建新能源货车的智能网联系统有重要意义。
In V2X intelligent network environment,the dispatching system of new energy trucks needs real-time dynamic information.The system under traditional particle swarm scheduling method is prone to fall into local optimum and low solution efficienty.An improved particle swarm scheduling method for new energy trucks is proposed on the basis of multi-objective optiminaztion research.The inertia weight update method is improved so that the inertia weight decreases non-linearly,and the risk of the system falling into local optimum is reduced.A priori path encoding method is designed and optimized,the solution efficiency of the algorithm is improved,and the energy consumption of new energy trucks is reduced.The simulation results show that the total path length,path smoothness,and algorithm convergence speed are improved.In both static and dynamic environments,the reasonable scheduling of new energy trucks is achieved by the improved method.
