mmg模型控制下的船舶运动控制来仿真模拟船舶航迹舵控制的船舶操纵性方程(Ship motion control under MMG model control is used to simulate ship maneuvering equation controlled by ship track and rudder.)

说明：  将一个50Hz的干扰信号加入到白噪声中，然后对合成信号做fft，得到相应的幅频谱图和相位谱图。(A 50 Hz interference signal is added to the white noise, and then the composite signal is FFT to get the corresponding amplitude spectrum and phase spectrum.)

对连续波雷达系统从数据建模到后续处理最后检测目标(For continuous wave radar system, from data modeling to subsequent processing, final detection target.)

节点度是指和该节点相关联的边的条数，又称关联度。 特别地，对于有向图， 节点的入度 是指进入该节点的边的条数; 节点的出度是指从该节点出发的边的条数。(Node degree refers to the number of edges associated with the node, also known as the degree of association. In particular, for a directed graph, The ingress of a node is the number of edges entering the node; The out-degree of a node is the number of edges that start from that node.)

机械动力学进行模态分析，频响应分析等动力学的分析(Modal analysis, frequency response analysis and other dynamic analysis of mechanical dynamics.)

一个水下无人自主航行器（AUV）的MATLAB/simulink仿真程序，写得很详细，有附带的s函数和m文件供参考学习。(A MATLAB / Simulink simulation program for Unmanned Unmanned Unmanned Underwater Vehicle (AUV) is written in great detail, with s functions and M files attached for reference.)

对于非线性模型的跟踪预估问题，摒弃额对非线性函数进行线性化的做法，采用无迹变换处理均值和方差的非线性传递问题。(For the tracking and prediction problem of the nonlinear model, the linearization of the non-linear function is abandoned, and the traceless transformation is used to deal with the non-linear transfer of mean and variance.)
