Shape variation of the Gaussian pulse

在matlab环境下对图像进行四叉树分解，在此基础上对图像进行分析(In the matlab environment, an image quad-tree decomposition, in this based on image analysis)

this file contain models for modelling and simulation of nonlinear motor control. in this simulation dq frame is used to model.

This m file performs the QPSK transmission and reception.

说明：  柔性连接倒立摆状态方程及开环阶跃响应

要求使用继电自整定方法对其实施自适应PID控制。 1、选择采样时间0.1s，把对象离散化。 2、加继电（开关）控制，测量对象的Tc,Kc。 3、利用ZIEGLER-NICHOLS 公式表，确定PID参数。 4、实现闭环控制。 5、根据调节效果，修正PID参数。 (Require the use of relay tuning methods for its implementation of the adaptive PID control. 1, select the sampling time 0.1s, the discrete objects. 2, plus relay (switch) control, measurement object Tc, Kc. 3, using ZIEGLER-NICHOLS formula table, determine the PID parameters. 4, closed loop. 5, according to moderating effect, the amendment PID parameters.)

Kendall M检验 主要用于趋势分析(Kendall M testing mainly used in trend analysis)

IIR滤波器设计 一、 实验目的 1、 掌握冲激响应法和双线性变换法设计IIR滤波器的原理及具体设计方法，熟悉用双线性设计法设计低通、带通和高通IIR数字滤波器的计算机程序； 2、 熟悉模拟Butterworth滤波器和Chebyshev滤波器的设计，掌握冲激响应法和双线性变换法设计数字IIR滤波器的方法。 (IR filter design, the purpose of the experiment master IIR filter impulse response method and the bilinear transform design principles and specific design method, familiar with the the bilinear design method to design low pass, band-pass and high-pass IIR digital filter is a computer program familiar analog Butterworth filter and Chebyshev filter design, master the impulse response method and the bilinear transform design digital IIR filter method.)

说明：   A code for basic digital image processing

very useful for inverter design in power electronics
