expfft

用split-step方法求解非线性薛定谔(NLS)方程的例子(This code solves the NLS equation with the split-step method)

这是关于微电网中下垂控制的仿真模型，模型中两个微电源均采用了下垂控制方法。(This model is about the droop control method in microgrid.)

节点导纳矩阵求解，输入节点数、支路数以及支路信息，即可求得节点导纳。(Node admittance matrix solver, the input nodes, number of branches and branch information, the node can be obtained admittance.)

说明：  确定性系统中建立一个跟踪系统让稳态误差变成0 ( This script demonstrates designing a tracking system with feedback and gain compensation to bring steady-state error to 0 and a settling time of 2.5 seconds. The response to a unit step is simulated and plotted to compare the system before and after compensation. This uses the STEP function from the system id toolbox and also ODE45 function to compute the step response.)

MATLAB中实现PID控制系统的，改变输入r(k）分别为阶跃信号、三角波、方波。(MATLAB to achieve PID control system, change the input r (k) are step signal, triangle wave, square wave.)

Chemical Process Control a First Course with Matlab - P.C. Chau

一个简单的三相全桥整流器电路(A simple three-phase full-bridge rectifier circuit)

this is a book on practical feedback control and not on system theory generally.feedback is used in control systems for two reasons,it use matlab.

说明：  使用matlab进行图象处理的经典命令.(picture command)

装箱问题的FFD代码，很有用的，大家试试(FFD bin-packing problem of the code, looking for a long time, we try)
