Real-time control for a magnetorheological shock absorber in a driver seat

Bogdan Sapiński
The paper summarizes the author's research study on real-time control of a magnetorheological shock absorber (MRA) in a driver seat. The performance of the MRA for vibration and shock isolation of the driver seat was investigated experimentally in open loop and feedback system configurations. Real-time controllers for MRAs with on-off and continuously variable control schemes were developed in the integrated design and control environment of MATLAB/Simulink. The sensors used in experiments were tested to see how reconstructed velocity signals should affect output signals of the controllers to the MRA.
