Abstract

The robust H_∞ bipartite consensus problem is studied for a class of nonlinear time-varying multi-agent systems(MASs) with parameter uncertainties and external disturbances over signed networks. Following the thought of dealing with uncertainties in robust control, the considered system is transformed into a time-invariant dynamical model with norm-bounded parameter uncertainties. The robust bipartite consensus is converted to a reduced-order H_∞ control problem. Based on the Lyapunov stability theory, sufficient conditions in linear matrix inequalities(LMIs) are obtained for the robust bipartite consensus of MASs with desired H_∞ performance. Moreover, the design procedure of a distributed static output feedback controller is shown. Furthermore, an application for two-degree-of-freedom(2-DOF) planar mobile robots is presented to illustrate the effectiveness of the proposed controller.
