Trajectory planning and control for multiple-vehicles systems

Abstract

Algorithms for trajectory planning and control for a multiple-vehicles system are investigated. An issue of designing collision-free trajectories on a group of crossing paths is tackled. The trajectories are modeled as a set of via-points coupled with their associated achieving time. Furthermore, a tracking controller design dealing with actuators constraints and all via points' achieve times is proposed. By applying the controller, each vehicle is guaranteed to get closer to the desired via-points without any obstacle-avoidance motions. Simulation results showing the generated trajectories and tracking performance is presented. © 2011 IEEE.
