基于支持向量机的CVT压力传感器误差补偿(Error Compensation of CVT Pressure Sensor Based on Support Vector Machine)
无级变速器 压力传感器 误差补偿
2009/8/11
针对无级变速器(CVT)压力传感器测量误差较大的问题,提出了一种应用支持向量机(SVM)建立误差补偿模型的方法。在分析引起测量误差因素的基础上,确立了误差补偿模型的输入、输出基本结构;通过试验构建训练样本集,并完成误差补偿模型的训练,在训练过程中,通过遗传算法对模型参数进行了优化。试验结果表明,设计的误差补偿模型可以有效提高传感器的线性度,并可以把最大绝对误差从0.5MPa降至0.15MPa,显著...
