| 摘 要： | 测试系统的非线性动态补偿是仪器技术的一个重要方面．采用BP神经网络对测试系统进行动态补偿．BP神经网络的结果决定于网络输入、隐层和输出节点．由于其非线性映射特性，BP神经网络完全能够反映测试系统的动态响应特性．采用了收敛速度较快的递推预报误差算法训练神经网络．试验结果表明，BP神经网络的特性完全能够满足测试系统的动态补偿要求．表明本文的方法是有效的．

| Abstract: | Nonlinear dynamic compensation of measurement systems is an important aspect in the field of instrument technique.The back propagation(BP) neural network is proposed for nonlinear dynamic compensation of measurement systems,as its architecture is determined only by the number of nodes in the input,hidden and output layers.With the nonlinear mapping behavior,the BP neural network can catch up with the dynamic response of the system.A recursive prediction error algorithm which converges fast is applied to train the BP neural network.Experimental results show that the performance of the BP neural network model conforms to the measurement system to be compensated,proving the method is not only effective but of high precision. |
