【摘要】：石灰作为重要的工业原材料,石灰通过石灰窑煅烧而来,由于石灰窑温度控制系统具有大纯滞后、非线性、严重耦合等特征,会影响石灰石煅烧温度的稳定性,从而影响石灰的活性。针对普通的PID控制算法鲁棒性较差,很难得到满意的控制效果,因此提出了模糊免疫自适应PID-Smith预估控制方法来控制石灰石的煅烧温度。在模糊控制理论和Smith控制理论的基础上,分别介绍了模糊免疫自适应PID控制器和Smith预估控制器,最后将两者相结合,在Matlab中的Simulink平台上搭建了控制模型,并进行了仿真。仿真结果表明,模糊免疫自适应PID-Smith控制方法能使石灰窑煅烧温度快速稳定,鲁棒性强,并且超调量小。
[Abstract]:Lime, as an important industrial raw material, is calcined by lime kiln. Because the temperature control system of lime kiln has the characteristics of large time delay, nonlinearity and serious coupling, it will affect the stability of limestone calcination temperature. Thus, the activity of lime is affected. In view of the poor robustness of the ordinary PID control algorithm, it is difficult to obtain satisfactory control effect. Therefore, a fuzzy immune adaptive PID-Smith predictive control method is proposed to control the calcination temperature of limestone. On the basis of fuzzy control theory and Smith control theory, fuzzy immune adaptive PID controller and Smith predictive controller are introduced respectively. Finally, the control model is built on the Simulink platform of Matlab and simulated. The simulation results show that the fuzzy immune adaptive PID-Smith control method can make the calcination temperature of lime kiln fast stable, robust and small overshoot.
