英文摘要

      The design of the given time consensus protocol is investigated for network-connected systems with random Markov jump topologies, communication delays and external disturbances. Because of the theory of short time, in defining the given time consensus protocol we relax the requirement that the disagreement dynamics will converge to zero asymptotically. Instead, we only need the disagreement dynamics of interconnected networks stays within a given bound over a finite time interval. In one step followed, we develop the algorithm for the given time consensus protocol based on this definition. Thus, we not only provide an idea for lowering the conservatism of asymptotical convergence to zero in the time domain, but also make the design of control protocol more general in application by adopting the proposed method of model transformation. The effectiveness of the proposed consensus protocol is demonstrated by simulation examples.
