摘要
针对时空耦合系统控制精度不高的问题,提出一种空间变论域自适应时空耦合模糊控制器设计方法。首先基于时空耦合模糊集建立随空间物理变化的初始论域,并设计时空耦合论域伸缩因子在线实时调整模糊空间论域;其次采用变主导空间点的方法,分段调节空间加权因子,设计空间加权因子调节算法;最后通过仿真算例对方法进行验证。
Considering the poor control precision of spatio-temporal coupling system and based on spatial vari- able universe, a method to design adaptive spatio-temporal coupling fuzzy controller was proposed, in which, having spatio-temporal coupling fuzzy set based to establish an initial domain which changing with the space＇ s physical process, and the contraction-expansion factor of spatio-temporal fuzzy variable domain designed to ad- just fuzzy spatial domain online at real time ; and making use of change leading space point method to section- ally regulate spatial weighting factor and to design its adjustment algorithm. The simulation result verifies the effectiveness of this method.
