Abstract

This project is attempts to controls a stable tracking control for wheeled mobile robot with non-holonomic velocity constraints. Non-holonomic constraints are the constraints on the velocity of the system which cannot be integrated into position constraints that can be used to reduce the number of generalized coordinates. In this project, the application of kinematics controller is examined and analysed. The controller is using Lyapunov method which is a successful method in kinematics stabilization. In order to avoid any slippage, a velocity/acceleration limitation scheme was introduced. The control rule that apply in this project are robot-independent and hence can be applied to various kind of robot. Linearizing the system's differential equation is useful to decide parameters for critical damping for a small disturbance. The wheeled mobile robot used in this project is a tri-cycle type. All simulations in this project are performed using SIMULINK/MATLAB.
