First  an equivalent mathematic model of tracking error is established. Then  the equivalent sine signal is inputted to the equivalent model  and the outputs are sampled. The results of evaluating the tracking performance are obtained based on the statistical calculation of output produced by equivalent model. Equivalent model using the BP (Backprogration) neural network structure is identified. The training method of BP neural network adopts the LM (Levenberg-Marquardt) algorithm for the sake of speeding up training process. The BP neural network is trained and tested by using the training and testing samples gotten from the simulation model of optoelectronic theodolite tracking system under MATLAB/SIMULINK. The estimate errors of equivalent model including average error  maximum error and standard error are 2.5872e-0060  2.8 and 1.9. The results show that the equivalent model identified based on BP neural network meets the needs of evaluating the tracking performance of optoelectronic theodolite. The accurate evaluation of tracking performance is achieved. 2009 SPIE.   On the separable nonlinear least squares problems 期刊论文  OAI收割 JOURNAL OF COMPUTATIONAL MATHEMATICS, 2008, 卷号: 26, 期号: 3, 页码: 390-403 作者:  Liu, Xin;  Yuan, Yaxiang   |  收藏  |  浏览/下载：20/0  |  提交时间：2018/07/30 separable nonlinear least squares problem  variable projection method  Gauss-Newton method  Levenberg-Marquardt method  trust region method  asymptotical convergence rate  data fitting   A smoothing Levenberg-Marquardt method for NCP 期刊论文  OAI收割 APPLIED MATHEMATICS AND COMPUTATION, 2006, 卷号: 178, 期号: 2, 页码: 212-228 作者:  Zhang, Ju-liang;  Zhang, Xiangsun   |  收藏  |  浏览/下载：24/0  |  提交时间：2018/07/30 NCP  Levenberg-Marquardt method  smoothing technique  P-0 matrix  superlinear convergence   On the quadratic convergence of the Levenberg-Marquardt method without nonsingularity assumption 期刊论文  OAI收割 COMPUTING, 2005, 卷号: 74, 期号: 1, 页码: 23-39 作者:  Fan, JY;  Yuan, YX   |  收藏  |  浏览/下载：18/0  |  提交时间：2018/07/30 nonlinear equations  Levenberg-Marquardt method  quadratic convergence
