摘要

尝试量化优化磁链控制所能获得的电动汽车效率改进。在稳态转速-转矩工作点和标准工况下，对恒流比控制策略和真最优磁链控制策略进行了评价和比较。这是通过使用电动汽车的计算机辅助分析程序来完成的。分析了两种不同的系统;具有直流电机驱动的小型车辆，以及具有感应电机驱动的大型车辆。恒流比控制策略是直流电机真正最优控制的一种简单替代方案。驾驶周期计算表明，优化磁链控制后，效率提高了5-6%。

Efficiency analysis of electric vehicles, with emphasis on efficiency optimized excitation

An attempt is made to quantify the efficiency improvements in electric vehicles which can be obtained with optimized flux control. A constant current ratio control strategy and a true optimum flux control strategy are evaluated and compared in stationary speed-torque working points and for standard driving cycles. This is done by the use of a computer-assisting analysis program for electric vehicles. Two different systems are analyzed; a smaller vehicle with a DC motor drive, and a larger vehicle with an induction motor drive. The constant current ratio control strategy is shown to be a simple alternative to true optimum control for DC motors. Driving cycle calculations show efficiency improvements of up to 5-6% with optimized flux control.<>
