针对电站中速磨的控制难题,提出了一种模糊状态反馈跟踪控制方案。利用内模原理的特性来改善模糊跟踪控制系统的性能,使得被控非线性对象的输出变量可以渐进跟踪期望的变化轨迹。采用T-S建模方法来对中速磨进行建模并得到其T-S模糊模型。针对中速磨的T-S模糊模型设计模糊状态反馈跟踪控制系统并进行仿真,结果表明系统的输出可以很好地跟踪给定的轨迹。
Aimed at the control problem of medium speed mill, a fuzzy state feedback tracking control scheme is proposed. The characteristics of the internal model principle are used to improve the performance of the fuzzy tracking control system so that the output variable of the controlled nonlinear object can track the expected change trajectory gradually. T-S modeling method is used to model medium-speed mill and obtain its T-S fuzzy model. Aiming at the T-S fuzzy model of medium speed mill, a fuzzy state feedback tracking control system is designed and simulated. The results show that the output of the system can track a given trajectory well.
