说明：  通过本程序，可以将地震数据由ibm格式转为ieee格式，(form seisdate form ibm to ieee )

对于非线性时变工业过程对象，首先建立模型集来覆盖被控对象动态特性，分别建立相应的内模控制器，在系统变工况运行时，进行多模型加权自适应控制，与传统单内模控制相比，控制效果明显提高。(For the nonlinear and time-varying industrial process object, first ，we build model set to cover the dynamic characteristics of the object, then,set up a corresponding internal model controller respectively.When the system operation mode is running, multiple model weighted adaptive control has been used,and compared with the traditional single internal model control,it has improved obviously. )

播放音乐，利用matlab来播放音乐，很好的一个代码(music play)

通过给出的随机过程，该随机过程是由3个实正弦信号组成，归一化频率分别为0.1,0.25,0.27，其中相位是相互独立在【0,2*pi】上分布的随机相位；噪声是均值为0、方差为1的实高斯白噪声，信噪比为30db,30db,27db,观测样本数为N，通过bartlett法，Welch法，周期图法计算随机过程的概率谱(Given by stochastic process, the stochastic process is composed of three real sine signal, the normalized frequency were 0.1, 0.25, 0.27, including phase is independent in [0, 2* PI] on the distribution of random phase Noise variance is the mean to 0, 1 real gaussian white noise, signal to noise ratio of 30 db, 30 db, db, and the observation sample for N, by bartlett, Welch, periodogram spectrum method to calculate the probability of the random process)
