Abstract:

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. The problem of motion control is challenging because it is a non-holonomic 4-degree complex system (for a multi-trailer system, n + 3 degrees freedom), and the kinematics of this system are difficult to calculate due to the non-linearity and coupling of the relationships. This is an unstable dynamic system and increases the input restrictions of the robot by adding the Jack Knife phenomenon, even if we move it in a direct direction. So in this paper we are trying to use a off axial connection method to create a new idea for easy control for trajectory tracking time varying of a trailer system, or even extending it to a multi-trailer system, by turning it into a wheel mobile robot system that is very easy to control and You can create trailer inputs by creating a link through an off-axle link, with a non-linear backstepping control method of verification

Nonlinear Backward Tracking Control of an Articulated Mobile Robot with Off-Axle Hitching

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 usin...

Mobile robot predictive trajectory tracking

For a two-wheeled differentially driven mobile robot a trajectory tracking concept is developed. A trajectory is a time-indexed path in the plane, i.e. in the three-dimensional configuration space consisting of position and orientation. Due to the nonholonomic nature of a rolling wheel, the system cannot be stabilized by a continuous time-invariant feedback or by feedback linearization. A novel...

Robust 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...

Nonholonomic Mobile Robot Trajectory Tracking using Hybrid Controller

A control scheme is being presented for the trajectory tracking of a nonholonomic kinematic model of mobile robots. As a kinematic model of mobile robots is nonlinear in nature, therefore, it is controlling is always being a difficult task. Thus, a control hybrid scheme comprises of fuzzy logic and PID (Proportional Integral Derivative) is being proposed, in which adaptive gains of PID controll...
