Abstract: For a multirobot system subjected to exogenous disturbance and with partial information given, a robust consensus algorithm is developed to solve the output consensus problems. The kinematic model of a differential wheeled mobile robot is presented first. According to the idea of combining global control with local control, the consensus based on a multiagent system is mathematically described. Then, a reasonable robust performance index is proposed, and utilizing H∞ robust control and differential game theory, a robust consensus algorithm is designed. An example is simulated to demonstrate that the proposed method can guarantee the velocity consensus autonomously for each robot and restrain disturbance.

Key words: robot, H∞ robust control, differential game, multiagent, consensus
