摘要
针对强耦合多变量非线性的磁悬浮轴承控制系统,提出了多模态智能控制算法,根据控制器的输入信号的大小、方向及其变化趋势等特征,采用不同的控制策略及相应的控制模式,提高了系统的稳定性.实验结果表明:在动态性能和控制精度等方面,多模态智能控制的效果均优于增量式PID的控制效果.
A nonlinear, strong coupling magnetic bearing system with multiple variables is studied in the paper. An algorithm of multi-mode intelligence control is presented. Based on the features of input signal, diHerent control plans can be carried out in the system. Compared with the PID control, experimental result shows that the multi-mode intelligence control has better dynamic properties and control precision.
