倒立摆的程序，很好的，大家可以看看，想要源程序的可以给我发e－mail(inverted pendulum procedures, good, we can see, wants the source can give me the e-mail)

用稳定边界法整定公式来求P,PI,PID的个参数，其中G是已知被校正系统的开环传递函数,kp为比例系数， Ti为积分时间常数，Td为微分时间常数，输入参量Gc为校正器传递函数，p为系统开环极点的个数（不计重根个数，即多重根只计一个根）(With the Stable Boundary tuning formula seeking P, PI, PID' s parameters, of which G is known to be corrected and the system of open-loop transfer function, kp is proportional coefficient, Ti the integral time constant, Td for the differential time constant, input parameters Gc for the corrector transfer function, p is the number of poles of open-loop system (excluding the number of multiple roots, that is a multiple root only to the root))

说明：  ofdm系统下的频偏估计算法，moose算法的仿真(Frequency Offset Estimation ofdm system simulation algorithm, moose algorithm)

基于fht的匹配追踪算法，算法速度要比fft快很多，提高了一个数量级(Fht based matching pursuit algorithm, the algorithm much faster speed than fft, an order of magnitude increase)

embedded system solution of vahid book is available.

我们的目的是将一个分数拆分成若干个分子是1分母是正整数的分数之和的形式。例如2/3可以拆分成1/2+1/6的形式。这里不考虑顺序，比如1/6+1/2和1/2+1/6相同。 输入p, q, a, n, 其中p/q为分数，对这个分数进行拆分，要求拆分的分数个数不能多于n个，所有分母的乘积不能大于a。求有多少种拆分方法? 输入：最多200组数据。在每行中都有四个数分别表示p, q, a, n，之间以空格隔开，并且满足p,q<=800，a<=12000，n<=7，最后以四个0做为输入的结束。 输入示例: 2 3 120 3 2 3 300 3 0 0 0 0 输出示例: 4 7 (Our aim is to split a fraction into a number of elements is a denominator is a positive integer fraction of the sum of form. For example, 2/3 can be split into 1/2+1/6 form. Not considered here, the order, such as 1/6+1/2 and 1/2+1/6 of the same. Input p, q, a, n, where p/q as a fraction of this split scores require no more than the number of split points n-all the product of the denominator can not be larger than a. How many kinds of demand split method? Input: Up to 200 sets of data. In each line has four numbers indicate the p, q, a, n, separated by a space between, and meet the p, q < = 800, a < = 12000, n < = 7, the end, four 0 as the input end. Input Example: 2,312,032,330,030,000 sample output: 47)
