中文摘要
      针对电动汽车感应电动机变频驱动系统存在的轻载低效问题,考虑电机定转子铜损和铁损,研究了感应电动机变频驱动系统效率优化控制算法．采用减小磁链搜索范围的方法,改进了黄金分割法在线搜索控制器,设计了以数字信号处理器TMS320LF2407为控制电路核心的实验系统,对损耗模型控制算法、黄金分割法和改进的黄金分割法在线搜索控制算法分别进行了对比实验研究．实验结果表明,两类控制策略都能够有效提高感应电动机变频驱动系统的运行效率;基于损耗模型的控制算法具有寻优速度快、磁链和转矩波动小的优点,而改进的黄金分割法搜索控制器算法简单,效率优化效果优于基于损耗模型的控制器;在线搜索控制算法不受电机参数变化及建模精度的影响,具有更为广泛的应用前景．
英文摘要
      Taking the copper loss and iron loss into account, the efficiency optimization control of induction motor (IM) drives for electric vehicles is studied to improve the motor efficiency under light load. The search-controller based on golden section algorithm is improved by reducing the search scope of rotor flux. An experimental system is built based on TMS320LF2407 DSP. Loss-model control algorithm and search-control algorithm based on golden section method and improved golden section method are compared through experimental research. The experimental results show that both of the control strategies can improve the motor efficiency remarkably. The loss-model controller has good characteristics of fast optimization speed and small torque and flux fluctuation. The algorithm of improved golden section search-controller is simple, and it can achieve higher efficiency than loss-model controller. Search-controller is independent of parameter variations and model precision, and it thus has broad application prospects.
