摘要
在当被控对象与模型失配情况下,Smith预估控制往往难以达到满意的效果。针对具有此种情况的纯滞后工业过程,提出了一种内模控制设计方法;通过仿真结果表明,内模控制能克服被控对象增益和时间常数变化对控制性能的影响,有较强的鲁棒性和抗干扰能力。
Smith predictor control cannot achieve a satisfactory performance during mismatcn Ol internal model with object model. An internal model control design for industrial process with pure delay is proposed,it makes internal model control is a proved technique. As shown by large number of simulation tests, internal model control can overcome the influence on control performance come from the gain variation and the time constant variation of the controlled object and it possesses better robustness and ability of anti-disturbance.
