| 中文摘要: |
| 针对某型车速传感器所面临的电磁兼容问题，分析了射频辐射产生的原因，提出了混沌神经网络电磁兼容优化设计算法。该方法采用多个待优化变量并行搜索的方式及反馈型的网络模式逐渐缩小搜索空间，直至找到全局最优解。实验表明，该算法能有效降低传感器射频能量的峰值，优化后的车速传感器电磁兼容性测试结果符合速度传感器通用技术条件的整体误差标准。 |

| Aiming at the electromagnetic compatibility problem faced by a certain type of vehicle speed sensor, the reason of radio frequency radiation is analyzed, and the optimization design algorithm of electromagnetic compatibility of chaotic neural network is put forward. In this method, we use the parallel search method for multiple variables which will be optimized and the feedback network model to narrow the search space to find the global optimal solution. The experimental results show that the proposed algorithm can effectively reduce the peak value of the RF energy of the sensor. The electromagnetic compatibility test results of the optimized vehicle speed sensor accord with the general error standard of the general technical condition of the speed sensor. |
