This paper investigates the cooperative robust parallel operation problem where a linear uncertain plant is collectively driven by multiple actuators that cooperate over directed graphs. In order to address both the uncertain parameters of the plant and the communication constraints imposed by the communication network, a distributed dynamic output feedback control law is devised based on the internal model principle. It is shown that the proposed control law can effectively achieve robust output regulation of the closed-loop system while ensuring plant input sharing among the actuators. The effectiveness of the proposed control law is demonstrated through a practical example.
