Nonlinear Backward Tracking Control of an Articulated Mobile Robot with Off-Axle Hitching
نویسنده
چکیده
This paper proposes a nonlinear path control for backward driving of a car-like mobile robot pushing trailer with off-axle hitching. The control law is constructed using high-gain design techniques and involves error coordinates expressed which are partially linked to the trailer and invariant properties with respect to the vehicle speed. The stability of the closed-loop system is analyzed using Lyapunov stability theory. Simulation results illustrate the effectiveness of the proposed controller. Key-Words: Articulated mobile robot, off-axle hitching, path following, nonlinear control, high-gain design

Trajectory Tracking Weeled Mobile Robot Using Backstepping Method with Connection off Axle Trailer
The connection of the tractor to the inactive trailer or motor vehicle causes a motion control problem when turning in the screw, forward or backward movements and high speeds. This is due to the inactive trailer being controlled by the tracking using a physical link that is not affected by the movement. Trailers usually take tracks under these conditions. This phenomenon is called Jack Knife. ...
متن کاملTrailer Steering Control of a Tractor-Trailer Robot
In this paper, we consider active trailer steering control as a means to improve the maneuverability of (long) truck–trailer combinations during cornering. Hereto, we formulate the problem of reducing the so-called swept path width during cornering and that of eliminating unsafe tail swing of the trailer as a tracking control problem. We present a kinematic tractor–trailer model including off-a...
متن کاملRobust Sliding Mode Controller for Trajectory Tracking and Attitude Control of a Nonholonomic Spherical Mobile Robot
Based on dynamic modeling, robust trajectory tracking control of attitude and position of a spherical mobile robot is proposed. In this paper, the spherical robot is composed of a spherical shell and three independent rotors which act as the inner driver mechanism. Owing to rolling without slipping assumption, the robot is subjected to two nonholonomic constraints. The state space representatio...
متن کاملCascaded VFO Control for Non-Standard N-Trailer Robots
Articulated mobile robots consisting of a tractor and passively off-hooked trailers belong to a class of highly nonlinear, nonholonomic, structurally unstable, differentially nonflat, and underactuated dynamic systems. Due to the mentioned properties of their kinematics, motion control problems related to N-trailer robots (N-trailers) are non-trivial and challenging. Cascaded control strategy p...
