This paper builds a multi-body dynamic model of an asymmetric variable sweep morphing aircraft and explores the idea of aircraft roll control by using asymmetric wing sweep angle change. This morphing aircraft is treated as a multi-body system because the large motion of wing segments makes the rigid-body approximation inadequate. Kane's method is used to(More)
The design of an adaptive controller and stability analysis of the corresponding closed loop system are discussed for a class of SISO systems based on the characteristic model method. The obtained characteristic model is a second-order slow time-varying linear system with a compress mapping function for the system modeling error. The pole placement method(More)
This paper deals with the leader-following consensus problem for a class of multi-agent systems with nonlinear dynamics and directed communication topology. Two distributed adaptive nonlinear control laws are proposed based on the relative state information between neighboring agents, which solve the leader-following consensus problem and the inverse(More)
This paper investigates the consensus control of a class of Lipchitz nonlinear multi-agent systems with communication time delay. The proposed control only uses relative state information of the system. An optimal consensus control is then identified through a careful exploitation of the structure of Laplacian matrix and semi-discretization method.
This paper proposes a robust nonlinear attitude control method for aircraft based on partitioned backstepping and input-to-state stability theory. With this strategy the coupling of the model attitude can be dealt naturally. A stable attitude control is realized semi-globally and the scheme has a good robust property subjected to external disturbances. The(More)
The objective of this study was to evaluate the antioxidant capacity of Lactobacillus plantarum ZLP001 and its effects on growth performance and antioxidant status in weaning piglets. The survival in hydrogen peroxide and free radical-scavenging activity of Lactobacillus plantarum ZLP001 were analysed in vitro. The Lactobacillus plantarum ZLP001 showed high(More)
