摘 要：This paper investigates the consensus for a class of first-order stochastic nonlinear multi-agent systems. Different from the related results, the systems allow serious unknown control coefficients and parametric unknowns in nonlinearities. To compensate the serious unknowns, a distributed time-varying consensus protocol is proposed. The key of the proposed protocol is to introduce a time-varying gain which is used to capture the serious unknowns as time increases. Based on the protocol, the almost sure consensus is achieved for the multi-agent systems under strongly connected graph. A simulation example is finally provided to verify the effectiveness of the theoretical results.
