说明：  关于增加高斯白噪声的代码，对信号加上高斯噪声的仿真(Gaussian white noise to increase the code, the signal plus Gaussian noise simulation)

该算法时LDPC码优化的好帮手。通过差分进化（DE）实现LDPC码度分布优化。给定码率，自动搜索最佳度分布。算法运算量较小，可以得到次优解。(The algorithm of LDPC code optimization is a good helper. Through differential evolution ( DE ) to realize LDPC code degree distribution optimization. Given rate, automatic search of optimal degree distribution. Algorithm can get smaller, suboptimal solution. )

本代码采用二次规划求解电力系统经济调度问题，具有快速的计算速度。(The attached code used to solve the economic dispatch problem for power system operation is easy-implemented and high-efficiency. Only for study. Thank you!)

PID仿真程序，只需要人工修改PID参数，及根据自身情况修改模型参数就可以轻松实现PID仿真。(PID code in matlab)

The remarkable advance in hydraulic and electrohydraulic power systems resulted in producing control valves of very short settling time. The rapid closure of hydraulic transmission lines leads to severe pressure surge. Thattached Simulink file is developed to evaluate the applicability of oleo-pneumatic accumulators for the protection against this phenomenon. A lumped parameter model was developed for the transmission line, assuming four lumps, considering the effect of line resistance, inertia and capacitance.
