Path tracking controller for a tractor with multiple trailers

Abstract

In this paper, the authors discuss an articulated vehicle robot consisting of one tractor and two trailers as actually used in industrial plants. Because of the articulated vehicle, one must consider the safety of the rear trailers. Therefore, the authors propose a new path tracking control system that can adjust velocity and steering angle by fuzzy reasoning and prediction as well as modify the steering angle with the margin of deviation for the safety of rear trailers.
