Abstract: In this study, the control methods of a semi-active magneto-rheological (MR) suspension system for an armoured military vehicle were compared. System modelling and testing procedures were described and then control algorithms were tested and observed on a quarter car test setup, this setup was modified from passive to semi-active system. For tests and simulations, a special off-road profile was formed. This profile was formed depending on the standard military test courses and terrains. During the observation, control ability and personnel comfort were observed as main subjects. Finally, depending on the test results, displacements, accelerations and their effects on subsystems were compared and construed as advantages and disadvantages.

Keywords: magneto-rheological; semi-active; armoured vehicle; hybrid control; clipped control.
