According to the literature review, inertia may cause due to the overdriven, slip of the WMRS, over force, sharp turn in cornering and emergency stop. Therefore, this research has taken the initiative to design and model a dynamic control to cater the inertia factors happen on the mobile robot during cornering motions. An Omnidirectional Mecanum Wheeled Mobile Robot (OMWMR) is selected as a platform for modelling and control design since this configuration is favourable for confine area application. Kinematics of OMWMR is modelled by considering the mecanum wheel coordination to the centre body of the robot frame and further with dynamic modelling and analysis. With reference to the problem statements in the kinematics and dynamics analyses, inertia shaping technique is designed by using impedance control approach where the difference of vehicle forces is considered as interaction force of the vehicle have indirectly controlled through the velocities of the vehicle. The research scope is emphasized on the vertical (X-axis) and horizontal (Y-axis) of the OMWMR motions during cornering periods where the inertia is a critical state. Since velocity state is the lowest order for the wheeled type system kinematics system, the velocity-based impedance control is derived proposed as the dynamic control for OMWMR system to cater the mentioned issue in cornering period. This proposed dynamic control concerning both stiffness and damping ratio as parameters tuning. The control objective is to shape the velocity input of the OMWMR system during cornering period with reference to the different force inputs on both X and Y axes of the system where the difference torques on each wheel with friction torque were considered. As for the verification, the proposed dynamic control was modelled and simulated with OMWMR system model plant. The results show that the proposed impedance control is able to reduce the different forces on each X and Y axes of the robot by reducing its velocity inputs at the cornering period. On the other hand, kinetic energy reduction at the same period influenced by robot’s velocities proved that the proposed control has reduced the inertia effect on the OMWMR system. specialized Norsharimie Mat Adam Faculty of Electrical and Electronics Engineering Thesis (Master of Science) -- Universiti Malaysia Pahang – 2018 Includes bibliographical references Faculty of Electrical and Electronics Engineering Dissertations Universities and colleges Disertations Theses THE0008050(Local) UMP 190212 20251117113438.0 vtls000105479 eng
