Abstract: Targeting at a class of discrete Multi-Agent Systems (MASs) subject to actuator saturations, a novel consensus controller based on Linear Matrix Inequalities (LMIs) is proposed and the existence of the solution for the LMI is examined. Due to the actuator saturation, the consensus control problem of MASs is related to the initial states of agents. Different controllers may tolerate different ranges of initial states. In order to quantitatively analyze the effects caused by the range of initial states, this paper introduces the concept of Domain of Attraction (DOA) to evaluate the controllers and, subsequently, the controller parameters are optimized to enlarge the DOA. Finally, simulation examples are provided to illustrate the effectiveness of the proposed controller.
