最优状态估计，包括卡尔曼滤波、H_inf、UKF(optimal state estimation)

改进斥力场函数和使用虚拟中间目标点法解决传统人工势场法局部极小值问题(Improving the repulsive force field function and using the virtual intermediate target point method to solve the local minimum problem of traditional artificial potential field method)

一种简单的A*寻路算法，可在命令行按要求输入相应起点和终点的坐标。适合于初学者(A simple A* algorithm for path planning, which can input the coordinates of the starting point and end point on the command line as required. It is suitable for beginners.)

this document present how we use butterworth ,chybi1,chiby2 and recursif fiter using matlab

ALOGAM computes the logarithm of the Gamma function.

说明：  dijkstra算法解决路径规划问题，求解任意两点之间的最小距离(Dijkstra s Shortest Path Algorithm calculates the shortest path and distance between two nodes on a map )

BP神经网络：是一种按误差逆传播算法训练的多层前馈网络，是目前应用最广泛的神经网络模型之一。BP网络能学习和存贮大量的输入-输出模式映射关系，而无需事前揭示描述这种映射关系的数学方程。它的学习规则是使用最速下降法，通过反向传播来不断调整网络的权值和阈值，使网络的误差平方和最小。BP神经网络模型拓扑结构包括输入层（input）、隐层(hide layer)和输出层(output layer)。(BP neural network: a Press the front back propagation algorithm to train multilayer feedforward network is one of the most widely used neural network model. BP network can learn and store large amounts of input- output mode mappings without prior reveal mathematical equations that describe this map. It' s learning rule is to use the steepest descent method, through a reverse spread to constantly adjust the network weights and thresholds, so that the minimum squared error of the network. BP neural network topology, including the input layer (input), hidden layer (hide layer) and output layer (output layer).)

说明：  本文主要是通过Buck变换器推导出移相全桥变换器的小信号电路模型，接着用MATLAB软件进行仿 真，来判断系统的稳定性。 ( This paper is mainly through the Buck converter is deduced the whole bridge converter phase shifting small signal circuit model, then the MATLAB software to copy True, to judge the stability of the system.)
