电池模型的参数辨识，利用端电压的实际值和估计值，得到相关的7个参数(Parameter identification of battery model)

说明：  给图像添加噪声，驱除噪声，具体的说就是先添加高斯噪声等等，然后通过中值滤波，自适应滤波等等(Add noise to the image, get rid of noise。Specifically, it is the first toadd Gaussian noise, etc., and then median filtering, adaptive filtering, etc. )

[model] = SVMTRAIN(X, Y, C, kernelFunction, tol, max_passes) trains an SVM classifier and returns trained model. X is the matrix of training examples. Each row is a training example, and the jth column holds the jth feature. Y is a column matrix containing 1 for positive examples and 0 for negative examples. C is the standard SVM regularization parameter. tol is a tolerance value used for determining equality of floating point numbers. max_passes controls the number of iterations over the dataset (without changes to alpha) before the algorithm quits.

将波纹钢板桥涵结构简化为单位宽度的固支圆弧梁,同时考虑波纹钢板桥涵结构和土的共同作用,首次建立了该结构的计算模型,推导了该结构位移、应力的解析解.实例计算结果表明:理论计算结果和现场实测结果相当吻合.在此基础上,编制MATLAB程序,进一步分析波纹板厚、波峰高度、波长、结构半径,土体自重、侧压力系数,以及弹性模量对结构位移、应力的影响,为该结构优化设计和施工提供了理论依据.(The simplified structure of corrugated steel culvert unit width clamped circular beam, taking into account the corrugated steel culvert structure and interaction of soil for the first time to establish a computational model of the structure, the structural displacement derived analytical solution of stress. Example calculation the results show that: the theoretical calculations and field measurement results are quite consistent on this basis, the preparation of the MATLAB program, further analysis of corrugated sheet thickness, wave height, wavelength, structure radius, the weight of soil, lateral pressure coefficient, and elastic modulus of the structure. displacement, the impact of stress for the structural optimization design and construction provides a theoretical basis.)
