摘要
介绍了基于ABS的间接胎压监测系统中使用的参数估计模型。结合最小二乘法思想,采用减小测量误差平方和的思路建模,当误差趋于独立零均值时等效为最优化问题。将估计法与模式搜索法结合估计识别监测参数。理论分析、实验验证模型有较好的精确性。
The design of the estimation schemes in indirect tire pressure monitoring system base on the ABS is introduced. In the spirit of a least squares method, it introduces a nonlinear estimation schemes which seek to minimize the measurement errors. It equivalents to the optimization problem when the error tends to independent, zero mean.Theoretical analysis and Matlab experimental results demonstrate the model provides good accuracy and efficiency.
