摘要
鉴于目前电动车普遍存在续程短的情况 ,首先从车辆的动力系统角度建立了较为系统的续程分析数学模型 ,并给出分析过程和分析实例 ,验证了模型的正确性。接着 ,就使用永磁有刷电动机为原动机的车辆 ,分析了在PWM占空比为 10 0 %时最大续程时系统动力特性。最后 ,利用最优控制理论 ,分析行车策略与续程的关系 ,并得出了若干重要结论。
In order to increase the EV rate distance,the model and process of calculating rate distance are proposed.In the EV driving system.permanent magnet DC motor is used as its driving motor.The dynamic characteristic under the condition of the maximum distance and 100% pulse duty cycle is analyzed.In the end,by using of the optimal control theory,the relation ship between driving strategy and rate distance is studied,and some important conclusions are obtained.
