PID CONTROLLER DESIGN FOR AN ACTIVE ANTI-ROLL BAR SYSTEM ON CARS

Abstract

The active anti-roll bar system is one of the solutions in cars to improve safety
for users, vehicles, and goods. The system can increase the vehicle's roll stability
by continuously generating a stable torque over time to avoid the effect of the
car's instability moments. In this article, the authors use a half car model, to
research and design a PID controller with the input signal being the road surfaces
q1, q2 and the vehicle's inertia force Fqt. To evaluate the performance of the
controller, the authors used specialized software Matlab - Simulink, surveying in
the time domain with important evaluation criteria such as vertical wheel
displacement, vehicle body displacement, vehicle body roll angle and vehicle
body roll angle speed.
