对于配电网重构的研究是很有用的，本例子相当有用，(Reconstruction of the distribution network is very useful, very useful in this case,)

When doing optimization, GA algorithm was initially selected, but the instability of the GA (or local optimization) is really frustrating, before and after the resulting difference can at times reach more than 30 , at that time due to time reasons, I chose to optimize 1000 times, then the minimum value of the most optimal solution. Although the problems are solved, but an academic, this style of running is pretty embarrassing. So, I downloaded a GA-PSO algorithm, try using the combination of GA and PSO optimizing strategies, results algorithm issues, efficiency and good. I downloaded the original algorithm, there is a problem is that it is aimed at all upper and lower limits of the design variables are the same, so I modified the program and improvements, you can now deal with upper and lower limits of the inconsistency problem and fix the bug. Now, program modifications, and share, hoping to be useful to you

matlab PID simple s model pid最简单的S模型，可以自己加入扫频信号，就可以看开环伯德图了(matlab PID simple s model)

该代码展示了如何通过数值方法估计某个量值的思路，方法具有新颖之处。。。望采纳(QUADGUI Demonstrate numerical evaluation of a definite integral. Q = QUADGUI(F,A,B) shows the steps in approximating the integral of F(x) from A to B by adaptive extrapolated Simpson s quadrature. The shaded area shows the integral over the current subinterval. The color switches to green when the desired accuracy is obtained.)
