| 摘 要： | 火电厂钢球磨煤机的负荷对象具有大滞后、慢时变、强非线性等复杂特性,采用常规控制方法难以获得满意的控制效果,本文提出了基于灰色预测的无模型自适应负荷控制方法.该方法融合了无模型控制的自适应、抗干扰特性与灰色预测模型的预测时延、抑制超调和快速稳定特性,它将灰色模型的预测结果代替负荷对象输出测量值,再进行无模型自适应闭环控制.仿真结果表明这种控制方法系统响应快、超调小、鲁棒性好、抗干扰能力强,可以有效解决大滞后、非线性及适应性等问题.

| Abstract: | The load object of ball mill in thermal power plant has complex traits of large time-delay,slow time-varying,strong nonlinearity and etc.It is difficult to obtain satisfactory control performance using conventional control methods.In this paper,a model-free adaptive control method based on gray prediction is introduced for load control.This control method combines the adaptive,anti-interference features of model-free control with the time-delay prediction,overshoot suppression and rapid stabling of gray pre... |
