在过程控制中，按偏差的比例（P）、积分（I）和微分（D）进行控制的PID控制器（亦称PID调节器）是应用最为广泛的一种自动控制器。(In process control, according to the percentage of deviation (P), Integral (I) and differential (D) control of PID controller (also known as PID regulators) is the most widely used of an automatic controller.)

一个很好的MATLAB教程,是用网页的形式写的,很好的学习资料,讲了很多例子与技巧(a good MATLAB Guide, the website is written in the form of good learning, used a lot of examples and techniques)

matlab code you can run it and its detail has been in to the file.for compiling you need octave for linux or matlab program to run it.

A 2by3 MIMO model using Simulink. The decoder uses zero forcing algorithm. Set in the workspace the modulation order (QAM modulation), Doppler shift, SNR in dB, bit rate, sample per frame, max number of bits and max number of errors before running the simulation. Works also with BERTool but change the BER variable to ErrorVec. Included in the file a BER session with multiple runs and a figure for several runs.
