Bounded Controllers for Decentralized Formation Control of Mobile Robots with Limited Sensing
نویسنده
چکیده
This paper presents a constructive method to design bounded cooperative controllers that force a group of N mobile robots with limited sensing ranges to stabilize at a desired location, and guarantee no collisions between the robots. The control development is based on new general potential functions, which attain the minimum value when the desired formation is achieved, and are equal to infinity when a collision between any robots occurs. Smooth and p times differential jump functions are introduced and embedded into the potential functions to deal with the robot limited sensing ranges. Formation tracking is also considered.

متن کاملLateral and Longitudinal Stability for Decentralized Formation Control
This paper analyzes the stability properties of a decentralized hybrid control system for maintaining formations. Utilizing only local sensing, the system assembles strings or ”platoons” of robots that has each robot maintaining a fixed bearing to its nearest neighbor. Using these platoons, the system is able to construct more complicated geometries. A piecewise linear controller based on bidir...

This thesis develops a hybrid decentralized formation control framework to coordinate multiple mobile robots with nonholonomic constraints. The proposed approach deploys a control theoretic bottom-up approach where, some low level behavior based controllers are coordinated by a discrete event system with supervisory control. The robots are required to navigate in an unstructured environment wit...
