熵权法的matlab实现，熵权”理论是一种客观赋权方法，它借用信息论中熵的概念。熵权是在给定评价对象集后各种评价指标值确定的情况下，各指标在竞争意义上的相对激烈程度，从信息角度考虑，它代表该评价指标在该问题中提供有效信息量的多寡程度，作为一种客观综合评价方法，它主要是根据各指标传递给决策者的信息量大小来确定其权数。(Matlab implementation of entropy weight method)

永磁同步电机加减速控制，电控部分，飞轮储能(Permanent magnet synchronous motor rotor acceleration and deceleration control)

信号稀疏表示是一种新兴的信号分析和综合方法，其目的就是在过完备字典中用尽可能少的原子来表示信号。采用时频原子字典的信号稀疏表示能够有效地揭示非平稳信号的时变特征。信号稀疏表示吸引了研究者的大量关注，这种方法已经被应用到信号处理的许多方面，例如非平稳信号分析，信号编码、识别与信号去噪等。(Signal sparse representation is a new method of signal analysis and synthesis, and its purpose is in over-complete dictionary of atoms using as little as possible to represent the signal. When using frequency atom dictionary signal sparse representation can effectively reveal the time-varying characteristics of non-stationary signals. Signal sparse representation attracted a lot of attention of researchers, this method has been applied to many aspects of signal processing, such as non-stationary signal analysis, signal encoding, recognition and signal denoising.)
