摘　　要：针对非线性、大滞后被控对象,提出了模糊控制与Smith预估控制器相结合的智能控制方法。结果表明,此控制器比常规控制器能有效地提高系统稳态精度,具有较强的鲁棒性,并且超调量小,相应速度快。With regard to non-linear, largetime-delayobject, a Fuzzy Smith intelligent method is proposed which combines smith controller and Fuzzy control.Simulation research shows that the newly developed controller has well robustness, faster response speed, smaller overshoot and can reduce the static error effectively.

关 键 词：大滞后 模糊控制 SMITH预估器
