云计算是一种商业计算模型。它将计算任务分布在大量计算机构成的资源池上，使各种应用系统能够根据需要获取计算力、存储空间和信息服务。 (Cloud computing is a business computing model. It computational tasks are distributed in a large number of computer resources of Ikegami, a variety of applications based on the need for computing power, storage space and information services.)

HSMM的计算功能实现在原来HMM的基础上解决了时间的限制，适用性更强(HSMM computing function of the original HMM solve the limit of time, on the basis of stronger applicability )

提取原始信号的功率谱就可以看出在哪个频带的能量比较高，噪声主要集中在哪里，这样就可以专门分析那个频带的噪声(The power extracted the spectrum of the original signal can be seen in which frequency band energy is high, the noise is mainly concentrated in where, so that it can be devoted to the analysis of the frequency band of noise)

用ode45求解悬臂梁的动力学方程，得到其变形(Use ode45 solving the dynamic equation of the beam, to get its deformation)

一种广义预测控制实例，内涵几个m文件，以及说明(An Example of Generalized Predictive Control)

MATLAB实现C均值聚类算法，未调用现有算法，完全由本人完成。(MATLAB C-means clustering algorithm, call the existing algorithm is not completely done by me.)

利用随机共振进行信号检测，本程序主要针对单频信号利用4节龙哥库塔实现共振检测(Stochastic resonance signal is detected, the program focused on the use of single-frequency signal section 4 Long Ge Kuta achieve resonance detection)

说明：  异步电机的精确控制和速度辨识是交流传动系统中重要问题。在该仿真系统中，电机转速采用易于检测的电机定子电压和电流得到转速MRAS辨识算法来估算。由于速度辨识算法中电压模型的纯积分环节会引起的误差积累和漂移问题，采用改进积分型转子磁链估算模型来解决。(The precise control and the speed identification of AC motor are the very important issues on AC drive system.In this system, induction motor is controlled by the direct torque control, stator flux is estimated by u-n model observer that is effective in the full range of speed, motor speed is estimated by MRAS speed identification algorithm that is depended on the voltage and the current of motor stator easily detected. The modified integral rotor flux estimation model is used to solve the problem that the normal model can be affected by the error accumulation and drift of integral calculation in the voltage model of conventional speed identification algorithm. )
