摘　　要：针对典型大时变时滞系统 ,设计新的鲁棒fuzzy_PID控制器 ,实现系统参数大范围失配情况下的闭环鲁棒稳定 ,并且使闭环系统达到设定值无静差跟踪及满意的动态性能 .现场应用效果良好 .A new robust fuzzy-PID controller for a class of typical systems with large time-varying time delay is developed. Using this controller, the robust stability of the closed-loop system is guaranteed for the unmatched parameters of the controlled plant on a large scale. And the capability of the system is optimized. The application results of this controller in a \{paper-making\} process have shown to be very good.
