标准粒子群算法，内含1个简单的适应度函数，可直接运行，没有错误(Standard particle swarm algorithm, containing a simple fitness function, can be directly run, no error)

MAGNITUDE AND PHASE RESPONSE OF HIGH AND LOWPASS FILTER

by ankush laddha。This system is active front end rectifier. It keeps the DC link at reference value, 400V in this case, even if load is suddenly changes. Also power factor is controllable so can act as STATCOM too. Control is based on synchronous frame theory and 2-level inverter is switched using Sine triangle PWM technique.(This system is active front end rectifier.

MATLAB CODE FOR DELTA MODULATION TECHNIQUE FOR ANY SIGNALS

说明：  利用Matlab编写程序实现以下功能：以多项式形式输入系统前向通路传递函数和反馈回路传递函数，计算系统开环增益，判定型别，根据控制系统劳斯稳定判据原理，列出得到的任意阶次系统的劳斯表，判定闭环系统稳定性，若不稳定给出具有正实部极点的数目。 （1）根据用户输入的稳定度a，计算稳定的开环增益K的范围； （2）确定系统的最大稳定度a,计算相应的开环增益K的值。 (The use of Matlab programming to achieve the following functions: polynomial in the form of input system transfer function to the path and feedback loop transfer function, system open-loop gain calculation to determine type, according to Routh stability criterion control system theory, has been listed in the system of arbitrary order Routh table to determine the stability of the closed-loop system, if the stability of a positive real part gives the number of poles. (1) According to the stability of the user to enter a, calculation of the stability of the open-loop gain of the scope of K (2) to determine the most stable system a, the calculation of the open-loop gain of the corresponding K value.)
