Necessary and sufficient conditions for solving consensus problems of double-integrator dynamics via sampled control. (English) Zbl 1204.93080
Summary: Consensus problems of double-integrator dynamics via sampled control are investigated. The sampled control protocol is induced from continuous-time linear consensus protocol by using periodic sampling technology and zero-order hold circuit. With the obtained sampled control protocol, the continuous-time multi-agent system is equivalently transformed into a linear discrete-time system. Necessary and sufficient conditions are given to guarantee that all the agents asymptotically travel with zero relative positions and common velocities. Furthermore, the consensus problem with continuous-time consensus protocol is re-analyzed. A necessary and sufficient condition is also obtained which is consistent with the special case that the sampling period tends to zero. The effectiveness of these algorithms is demonstrated through simulations.
