In this paper, we consider the leader-follower formation control problem for general multi-agent systems with Lipschitz nonlinearity and unknown disturbances. To deal with the disturbances, a disturbance observer-based control strategy is developed for each follower. Then, a time-varying formation protocol is proposed based on the relative state of the(More)
During soft landing process of planet lander, it will encounter many obstacles need to control precisely. For traditional off-line design, it's very hard to handle many constrains with uncertainty. So this paper give out an online trajectory planning and guidance method to realize the autonomous obstacle avoidance to achieve flight safety. This method is an(More)
