Chapter 5 Secure Control of Distributed Multiagent Systems

In the last few years, the consensus problem of multi-agent systems has received compelling attention in the control and system community due to its broad applications in many areas, such as unmanned vehicles [459], formation control [461] and flocking [468]. The basic objective of consensus is to design protocols, based on local information of agents, which guarantee that the states of all agents converge to a common value. The consensus protocol was initially designed for systems of first-order agents [469] and then extended to systems of second-order dynamics; see, e.g., [476], [472], [478] and references therein.

It has been shown that the first-order consensus ...

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
