چکیده

Abstract: Autonomous guidance of the mining vehicle is based on the path tracking algorithm that use pre-calculated desired paths. These paths are often calculated without taking into account the nonholonomic nature of the vehicle motion. As a result the calculated path might be not feasible and the path tracking controller will be required to correct the situation, deteriorating at the same time the overall performance of the guiding algorithm. In this paper we describe path-planning algorithms for articulated and skid steering vehicles used in mining applications. We propose numerically stable procedure for computing off-line the skidding and articulation angles. The results of these computations complement the conventional path-planing procedures and improve significantly the path-tracking precision, and overall guidance performance. Copyright c 2002 IFAC

Dynamitic Analysis of Skid Steering for Articulated Motor- driven Vehicle

The hydraulic steering mechanism can lead the vehicle’s hydraulic system more complex and the tire wear heavier in the process of steering, which is detrimental to the steering control of the articulated motordriven vehicle. Thus the skid steering mode is implemented in the articulated motor-driven vehicle in this paper. This mode can simplify the vehicle without steering cylinder and it is mor...

Flight Path Angle Steering with Lambert Guidance Reference

In this paper a new guidance technique for ballistic missiles and launch vehicles is proposed. Generally the Lambert guidance is used to generate missile nominal (correlated) parameters through powered flight to put it in a ballistic flight path. Because of uncertainties and undesired factors, the nominal position and velocity obtained by Lambert technique need to be followed in actual flight. ...

Tracking and Regulation Control of a Skid Steering Vehicle

Differentially driven skid-steering vehicles are often considered for navigation in outdoor terrains. However, the control of such vehicles is challenging because the wheels must skid laterally to follow a curved path, and motion stability can be lost as a result of excess skidding due to the position of the instantaneous center of rotation (ICR). To accommodate for the potential loss of stabil...

Modeling and Optimal Control of 4 Wheel Steering Vehicle Using LQR and its Comparison with 2 Wheel Steering Vehicle

In this paper, kinetic and kinematic modeling of a 4 wheel steering vehicle is done and its movement is controlled in an optimal way using Linear Quadratic Regulator (LQR). The results are compared with the same control of two-wheel steering case and the advantages are analyzed. In 4 wheel steering vehicles which are nowadays more applicable the number of controlling actuators are more than the...
