Abstract: Today, given the importance of vehicle rollover event and the high number of accidents in this area, in this paper, an attempt is made in the field of rollover prevention of the ground tour (GT) road vehicle equipped with a series of active variable-geometry suspension (SAVGS) using a proportional integral derivative (PID), fuzzy PID and linear quadratic regulator (LQR) controller. In the present study, Basics of controller design are reducing vertical body acceleration and, more importantly, for lowering the vehicle roll angle and overall angular accelerations to increase vehicle roll stability. In summary, this work, while improving the control purposes such as roll prevention over to the expected parameters of vehicle suspension, such as separating vibrations and ride comfort, reduces overall energy consumption by selecting type of the suspension used.

Keywords: series active variable-geometry suspension; SAVGS; series of active variable-geometry suspension; PID; proportional integral derivative; fuzzy PID; roll stability; rollover prevention; LQR; linear quadratic regulator.
