This paper addresses the leader-follower consensus problem of multi-agent systems with a time-invariant communication topology consisting of general linear node dynamics. A distributed observer-type consensus protocol based on relative output measurements is proposed. It is shown that the leader-follower consensus of multi-agent systems can be cast equivalently into the stability of a set of matrices...
Keyblock has been received a lot of attention in underground engineering because it loses its stability first after excavation. Block theory originally proposed by Shi could not build the geometric characteristics of keyblock and explain how to determine the precise locations of keyblock. Therefore, the Unwedge program based on keyblock theory could not predict complicated polyhedral block except...
