分析了转筒干燥机的干燥过程,提出了切合实际的一阶惯性兼时变纯延迟及可测干扰的系统模型。并针对系统所具有的特性提出相应的解决方案,应用K. J. Astrom所提出的自校正调节器原理,在转筒干燥机系统上实现了带有前馈补偿的自校正控制,经仿真结果验证该控制方法是可行的 The drying process of the drum dryer was analyzed. A practical first-order inertia-time-varying pure delay and measurable disturbance system model was proposed. And the corresponding solutions are put forward according to the characteristics of the system. By applying the principle of self-tuning regulator proposed by KJ Astrom, self-tuning control with feedforward compensation is realized on the drum dryer system. The simulation results show that the control The method is feasible
