analyze the problems we need to face in the actual speed environment, and provide a reference for the system design and the equipment placement. secondly, we focus on the study of vehicles detection algorithm and give a brief introduction of image pre-processing method.

finally, the good performance of speed model is proved once more with experimental data ( stator voltage and current). the simulation results show that the estimation speed trace the actual speed very well except the oscillations in low speed area.

最后采集实际的定子电压和定子电流数据输入该估计模型，验证其正确性，仿真结果证明除了估计速度在低速区有部分振荡，整体来说估计速度能够很好的跟踪实际转速。
