用遗传优化算法求解高次非线性方程组。代码中举例说明。(Optimization using genetic algorithm high nonlinear equations. Code example.)

this is matlab code for hmm

pid controleur with optimisation

首先用matlab实现了识别算法的仿真，因为只是对特定的数字组合的识别，所以非常的简单，放弃采用比较复杂的识别算法，采用最普通的像素比较的识别算法。(First, to achieve the recognition algorithm using matlab simulation, because the only identification of a specific combination of numbers, it is very simple, give up the use of more complex recognition algorithms compare the most common pixel identification algorithm.)

睫毛最优阈值化处理之后用基于连通域搜索的方法进行噪声点删除，主要用到函数bwareaopen，代码包含在jiemao.m文件中。(Optimal threshold eyelashes after treatment with the method based on connected local search to remove the noise points, mainly used in the function bwareaopen, the code contained in the jiemao.m file.)

用MATLAB编写求解伪距定位方程的程序，对实际数据进行处理，解算出接收机的位置及钟差信息。提供8个通道的两组数据如下，X, Y, Z 为WGS-84坐标系下各通道所跟踪卫星的坐标，Range为与之对应的校正后的伪距测量值。(Using MATLAB pseudorange positioning equation solver, and the actual data processing, solution and calculate the position of the receiver clock error information. 8 provides the following two data channels, X, Y, Z coordinates of the WGS-84 coordinate system of each channel of the satellite tracking, Range for the pseudo-range measurements corresponding corrected.)

针对锂离子电池，建立电池模型，对于电池剩余电量进行估算，采用安时积分法，效果还可以(The lithium ion battery, a battery model, to estimate the remaining battery power, the current time integral method, the effect can also be)
