| 摘 要： | 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0.5 MPa降至0.15 MPa,显著提高了压力传感器的性能和测量精度. |

| Abstract: | Aiming at the problem of greater measurement error of pressure sensor in continuously variable transmission(CVT),a method of establishing error compensation model using support vector machine(SVM) was presented.Firstly,the basic structure of error compensation model was determined based on the analysis of the factors inducing measurement error.Secondly,training set was constructed by experiment,and the error compensation model was trained with the training data. Finally,the model parameters were optimized b... |
