Further studies on impulsive consensus of multi-agent nonlinear systems with control gain error

In this paper, the impulsive consensus of multi-agent nonlinear systems with control gain error is further studied. The paper indicates that the condition in Theorem 1 of the original paper (Ma et al., 2015) [1] is not correct. To correct the mistake, the new version is given, which deletes one unnecessary coefficient in the inequality condition in the paper Ma et al. (2015) [1]. Moreover, two modified results (Theorem 2 and Theorem 3) are given to increase the practicality. Due to the modification of consensus condition, the new simulations are also given correspondingly to verify the effectiveness of the proposed methods.
