| Summary: | Magnetorheological (MR) brake is one of the brake-by-wire technologies which is
developed using MR fluid by immersing it in MR brake mechanism. This study deals with
the development of MR brake in order to characterize and implement control system for
shaft speed application. It began from the literature review of previous study on MR brake
and continue the development of MR brake with a test rig. The MR brake was
characterized at various current in order to obtain the brake torque during braking. In
addition, the MR brake was also characterized at various loads to study the response such
as angular velocity, brake torque and displacement responses. Next, the mathematical
model of MR brake was simulated and verified with the experimental data. Then, the study
continues with performance evaluation of shaft speed control using MR brake. There are
two controllers implemented and compared in order to study controller performance under
the influence of loads. Two types of controllers, On-Off and PID have been implemented
with MR Brake. According to the performance of both controllers, PID controller shows
better performance compare to On-Off controller. |
