An electronic experimental system is built in order to generate and record mechanical vibrations in controlled conditions, loads and faults. Mechanical faults are considered and introduced by bearings fixed on rotating shaft. A universal electric motor spins the shaft at known and imposed angular speed, acceleration sensors are used to measure the vibration, and the useful signals are introduced in...
In this paper an algorithm for trajectory-tracking with obstacle avoidance for autonomous vehicles is presented. The algorithm tracks a trajectory composed of an intended global trajectory that was previously generated and local obstacle avoidance trajectories that are created when an obstacle is detected by the laser. A discrete-time sliding-mode controller is used by the autonomous vehicle to follow...
In this paper a discrete-time sliding mode control for the trajectory tracking problem of wheeled mobile robots is presented. The wheeled mobile robot taken into account was Powerbot. PowerBot is a mobile platform with two differential driving wheels (2DW) and two balancing caster wheels. It is an automated guided vehicle specially designed and equipped for autonomous, intelligent delivery and handling...
A trajectory tracking controller based on the backstepping technique for the PowerBot wheeled mobile robot using the kinematic model is proposed in this paper. The PowerBot is an automated differential drive guided vehicle specially designed and equipped for autonomous, intelligent delivery and handling of large payloads. The PowerBot is an ideal platform for laboratory and research tasks involving...
A solution to trajectory-tracking control problem for a four-wheel-steering vehicle (4WS) is proposed using sliding-mode approach. The advantage of this controller over current control procedure is that it is applicable to a large class of vehicles with single or double steering and to a tracking velocity that is not necessarily constant. The sliding-mode approach make the solutions robust with respect...
