Delay Compensation on Fuzzy Trajectory Tracking Control of Omni-Directional Mobile Robots

This paper presents a delay compensator fuzzy control for trajectory tracking of omni-directional mobile robots. Fuzzy logic control (FLC) of the robots is a suitable strategy for dealing with model uncertainties, nonlinearities and disturbances.  On the other hand, in many robotic applications such as mobile robots, delay phenomenon is able to substantially deteriorate the behavior of system's...

A Directional Identification Method Based on Position and Posture of Head for an Omni-directional Mobile Wheelchair Robot

Trajectory Tracking for Omni-directional Mobile Robots Based on Restrictions of the Motor’s Velocities

In this paper, we propose an algorithm that combine the restriction on motor’s velocities and the kinematic model of Omni-Directional mobile robots to improve the trajectory’s following. The algorithm verifies the reference velocities of the robot and redefine them if necessary, in order to prevent possible saturation on motor’s velocities. Simulation results of the algorithm applied to an omni...

Trajectory Tracking Control Based on Adaptive Neural Dynamics for Four-wheel Drive Omni- Directional Mobile Robots

Article history: Received: 24.01.2014. Received in revised form: 05.03.2014. Accepted: 10.03.2014. There is usually the speed jump problem existing in conventional back-stepping tracking control for four-wheel drive omni-directional mobile robots, a trajectory tracking controller based on adaptive neural dynamics model is proposed. Because of the smoothness and boundedness of the output from th...
