摘要
研究通过试验辨识获得最优预瞄加速度驾驶员模型物理参数的方法。采用时域辨识方法确定模型传递函数,采用非线性最小二乘法确定传递函数中所包含的物理参数,利用已知目标函数优化预瞄时间和反应时间,针对仿真数据进行了辨识分析。结果表明,该方法对驾驶员模型物理参数的辨识具有良好的效果。
A method to identify the physical parameters of driver model for optimal preview acceleration by tests is presented. Firstly the transfer function of driver model is estimated by time-domain identification and the physical parameters of transfer function are determined by using nonlinear least squares method. Then the preview time and reaction time are optimized by a known objective function. Finally the method is verified by simulation da- ta. The results show that the method presented is very effective for the physical parameter identification of driver model.
