主要是利用归一化的方法进行位场边界识别，利用导数与周围最大值的比值来进行。(Mainly using the method of normalized potential field boundary identification, the use of derivative and the ratio of maximum to be around.)

一个比较典型的PID处理程序，在使用单片机作为控制cpu时，请稍作简化，具体的PID 参数必须由具体对象通过实验确定。由于单片机的处理速度和ram资源的限制，一般不采用浮点数运算， 而将所有参数全部用整数，运算到最后再除以一个2的N次方数据（相当于移位），作类似定点数运算，可 大大提高运算速度，根据控制精度的不同要求，当精度要求很高时，注意保留移位引起的“余数”，做好余 数补偿。这个程序只是一般常用pid算法的基本架构，没有包含输入输出处理部分。 (A typical PID process, using the microcontroller as a control cpu, make some simplification, the specific PID parameters must be determined experimentally by a specific object. As the chip processing speed and ram resource constraints, generally do not use floating-point operations, and all parameters of all integers, and divided by an operator to the last N-th power of 2 data (the equivalent of the shift) for a similar fixed-point operations, can greatly improve the speed of operation, according to the different requirements of precision control, when high precision, attention to retain the shift caused by the " remainder" and on the remainder of compensation. This procedure is commonly used basic structure pid algorithm, does not include input and output processing section.)

MATLAB下使用viterbi算法进行卷积码的仿真范例。可以用任意配置的卷积码。testConv.m启动仿真，其中用了两种卷积码(一个1/2和一个2/3卷积码）。若要使用硬判决，需修改metric.m文件。其他就没有什么要改的了。解压即可使用。(Under viterbi algorithm using MATLAB simulation examples of convolution codes. Can be used in any configuration of the convolutional code. testConv.m start the simulation, which used two convolution code (a 1/2 and a 2/3 convolutional code). To use a hard decision, modify metric.m file. Nothing else would want to change it. Extract can be used.)

The BCJR algorithm is an algorithm for maximum a posteriori decoding of error correcting codes defined on trellises (principally convolutional codes). The algorithm is named after its inventors: Bahl, Cocke, Jelinek and Raviv.[1] This algorithm is critical to modern iteratively-decoded error-correcting codes including turbo codes and low-density parity-check codes.

matlab编制的电力系统暂态稳定分析程序， 可计算潮流，机电暂态仿真。带算例，有说明书，鲁汶大学编制(MatDyn is a free Matlab based open source program to perform dynamic analysis of electric power systems. It is inspired by MATPOWER, a power flow and optimal power flow program in Matlab and shares its philosophy: “It is intended as a simulation tool for researchers and educators that is easy to use and modify.” [1]. The source code of MatDyn is available. Care has been taken to keep it well structured and easy to understand.)
