直扩系统自适应门限判决SIMULINK建模(DS system adaptive threshold decision SIMULINK modeling)

直角牛顿-拉夫逊法的电力系统潮流计算程序，希望能对大家有所帮助(At right angles to the Newton- Raphson method of power flow calculation program, we hope to help)

This is a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN - LEVEL coding is used instead of Huffman coding. Compression ratio is compared for each DCT method. Effect of coarse and fine quantization is also examined. The execution time of 2 DCT methods is also checked. In addition, most energatic DCT coefficients are also applied to examine the effect in MatLab 7.4.0 R2007a. Input is 9 gray scale pictures & output is 9*9=81 pictures to compare. Blocking effect is obvious. (This is a JPEG encoding & decoding program of still image. It does not use level shifting.

Using MATLAB and Simulink for Control System Simulation and Design

使用PID算法与FUZZYPID算法仿真并作比较，仿真证明，FUZZYPID效果要好于单纯PID调节(Using the PID algorithm and FUZZYPID algorithm simulation and compare simulation results show, FUZZYPID is better than the simple PID regulator)
