冷带轧机厚度控制系统的智能优化控制

针对冷带轧机AGC控制系统中存在的时变非线性和时滞以及传统PID控制参数不易调整的问题,提出将智能模糊自适应PID控制器用于厚度控制回路的优化控制方案.在原有PID控制器的基础上融合了模糊推理的功能,通过模糊推理控制器在线实时调整PID控制器的参数,以满足PID参数时变的要求.仿真试验结果表明,采用智能模糊自适应PID的控制系统调节时间短,超调量小,动静态性能优越,控制效果优于传统PID控制.

Intelligent Optimization Control of AGC System in the Cold Mill

Aimed at the problems of time lag,time change,big inertia,nonlinearity and the difficulty of PID controller parameters adjusting,the intelligent fuzzy adapted PID controller was put forward and applied in the AGC system.Add fuzzy reasoning on the original PID controller,adjust the parameters of the PID controller online by using the fuzzy reasoning controller in order to fulfill the requirement of the PID controller.The results of Matlab simulation show that the fuzzy selfadjusting PID controller has short ...
