控制系统的matlab程序六个。含有波特图，根轨迹图等等matlab函数的使用方法(Matlab process control system 6. Porter contain maps, root locus diagram and so on to use the matlab function)

该模糊控制器的特点是针对大延迟或纯滞后系统(加干扰)进行控制，利用matlab自带fuzzy工具箱，采用经典文献中的模糊控制规则，并附原理及效果图以供学习交流。(The fuzzy controller is characterized by delayed or for large time delay system (plus interference) control, using fuzzy toolbox matlab own, using the classical literature of fuzzy control rules, together with the principle and effect diagram for the exchange of learning.)

能够实现蚁群算法寻优的程序，可以直接运行，运行后出来收敛图(Ant colony optimization algorithm can achieve a program that can be run directly after running out of the convergence plan)
