Target Fencing Control of Multiple Mobile Robots Using Output Feedback Linearization

In this paper, we focus on a moving-target-fencing problem for a group of mobile robots with nonholonomic constraints. A local cooperative control law is proposed based on output feedback linearization. The proposed control law uses the relative angle and distance measurements from the target and its neighbors, as well as the bearing angle itself. This control law does not need to predefine a fencing formation, and it can assure the estimation for unknown target＇s velocity and collision avoidance. It is rigorously proved that the proposed control law ensures that the moving target is exponentially fenced into the convex hull of multiple robots. Finally, numerical simulations verify the effectiveness of the proposed control law.
