根据功率谱的原始定义编制的功率谱分析程序，相比于周期图、welch法等更简洁，但分辨率不高。(spectrum analysis based on self-correlation)

fault detection without protection

In this paper we present the usefulness of the algorithm DCT (Discrete cosine Transform) blocks applied level image compression JPEG (Joint Photographic Experts Goup). It has been shown that this algorithm is the most efficient in the case of compression because it has very good properties for compaction energy related values. As a basic principle we eliminate high frequencies and keep the low and medium without visibly affecting image. DCT in JPEG compression algorithm is encountered in practical applications such as face detection, skin color, facial recognition, iris, fingerprints

说明：  该算法连续系统的积分分离式PID算法,用MATlab开发，能够管直接运行,当控制量与设定值偏差较大时，取消积分作用，以免积分作用过大引起系统的稳定性降低。(The algorithm of the integral continuous system separate PID algorithm, developed using Matlab and can directly run the tube, when the control volume and settings deviation is larger, the abolition of integral action, so as not to cause too large integral role in the stability of the system lower.)
