Due to the interactions among coupled spatiotemporal subsystems, it is difficult to achieve the tracking control of the coupled spatiotemporal chaos. However, every subsystem of the coupled spatiotemporal chaos can be approximated by a set of fuzzy models, of which each represents a linearized model of the subsystem corresponding to the operating point of the controlled system. Based on these fuzzy models, an H∞ fuzzy tracking control scheme is suggested,where a linear matrix inequalities (LMI) is employed to represent the feedback controller. The parameters of controller are obtained by using convex optimization techniques of LMI. The model reference tracking control of the coupled spatiotemporal chaos is achieved, and the stability of the system is also guaranteed. The tracking performance is tested by simulation as an example.

大麦是全球第四大禾谷类作物,在全球范围内广泛种植。大麦历来是我国的主要农作物,近代在促进畜牧业和啤酒工业的的发展上发挥了积极的作用。由于各种原因,上世纪60年代以来,我国大麦种植面积锐减,当前的大麦生产量远远不能满足我国日益增长的啤酒和饲料生产的需求。改善大麦籽粒和麦芽品质对于促进我国大麦产业发展,增强啤酒大麦市场竞争力,提高啤酒工业生产效益具有重要的意义。啤酒大麦(麦芽)的品质指标主要有籽粒蛋白
