The multi-tracking problem of second-order multi-agent system with communication delay is investigated in this paper. An intermittent control protocol is proposed on the basis of only relative position measurement, where the information of agent is quantized before transmission using stochastic quantization scheme. On the basis of algebraic graph theory, stochastic quantization and stability theory, some necessary and sufficient conditions are obtained. It is proved that the multi-agent systems equipped with the designed protocol can track the desired trajectory. Case study illustrates the proposed algorithm can solve the multi-tacking problem effectively.
