水稻包节是指水稻植株叶鞘较长,茎节未外露。一般矮秆品种表现包节,高秆品种很少有这种特性。但多数矮秆品种的包节性,在高肥条件下种植,或经100ppm 赤霉酸处理后,茎秆显著的伸长,茎节外露,成了高秆露节品种,说明其包节性状不是由矮秆... 水稻包节是指水稻植株叶鞘较长,茎节未外露。一般矮秆品种表现包节,高秆品种很少有这种特性。但多数矮秆品种的包节性,在高肥条件下种植,或经100ppm 赤霉酸处理后,茎秆显著的伸长,茎节外露,成了高秆露节品种,说明其包节性状不是由矮秆基因决定,仅仅是一种表现型。 展开更多

This paper presents the containment analysis and design of heterogeneous linear multi-agent systems(MAS)with time-delay under the output regulation.The leaders are treated as exosystems and an modified output regulation error is designed,which can deal with more than one leader in containment control,then the containment problem will be turned into an output regulation problem.A novel analysis framework of the output regulation is proposed to design a dynamic state feedback control law for containment error and distributed observer when the agents cannot receive external system signal,which guarantees the convergence of all follower agents to the dynamic convex hull spanned by the leaders.The system stability for time-delay containment is proved by the output regulation method instead of the Lyapunov method.Finally,a numerical example is given to illustrate the validity of the theoretical results. 展开更多
