| 摘 要： | 基于中储式制粉系统的工作特性和控制难度，提出了把振动信号和差压信号相结合表征磨煤机的存煤量，并采用比例、积分、微分控制(PID)与内模控制相结合的控制球磨机负荷的串级控制模型。良好的仿真效果表明，这种方法能有效地提高系统的自适应能力，改善了系统的控制效果。内模控制与PID控制相结合的控制方式能广泛用于工业过程控制。

| Abstract: | The effect of simple PID control is not ideal for the toad control system of tube mill as a result of its strong nonlinearity, large kg and time-varying characteristics,in view of this situation,the cascade load control system of tube mill is presented.In this control system,vibration signal and differential pressure signal are combined to characterize the coal storage of tube mill,and the cascade control model with the combination of PID control and internal model is adopted. The fine simulation effect shows that,This design method may effectively inprove the control result of system. |
