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...
