Abstract
In this study, the design and control of a
hydraulic system based tire changer machine have been
analyzed and simulated using MATLAB/Simulink
Toolbox successfully. The machine have a displacement
input which is a leg pedal displacement in order to push
the piston of the pump to fed the motor with a pressured
hydraulic fluid to rotate the tire with an angular speed to
mount and dismount it. Augmentation based H4 and H2
optimal synthesis controllers have been used to improve
the performance of the machine. Comparison of the
proposed controllers for tracking a reference input speed
have been done using two reference inputs (step and
random) signals. Finally, the comparative simulation
results proved the effectiveness of the proposed tire
changer with synthesis controller in improving the settling
time and percentage overshoot.
