摘要(Abstract):
针对单一模型的控制算法往往存在鲁棒性差的问题,提出一种应用非线性模型的自适应模糊控制器。利用过程灰色预测模型,建立以预测误差和预测误差变化率为输入信号的二维预测模糊控制器。根据状态引入灰色预测模型步长的模糊决策机制,改善控制性能。
For poor robust control problem of single model,a multi-model adaptive fuzzy controller is put forward.Through the grey forecast model,it can easily achieve the two-dimensional fuzzy controller by means of the predicting error and rate of predicting error.The control performance will be improved by introduction of grey-step model of fuzzy decision-making mechanism based on state.
