| Abstract: | Active safety systems are increasingly being utilized in automobiles, including an active antiroll bar system. This paper aims to develop PID and LQR controllers for active antiroll bar systems in cars, with the goal of enhancing roll stability and contributing to the reduction of traffic accidents. First, the authors study the structure and develop a dynamic model of the active antiroll bar system in cars using an electrohydraulic actuator. Then, a general vibration model of the car equipped with a passive antiroll bar at the front and rear axles is constructed. Next, the authors develop an active antiroll bar system for the general integrated car model using electro‐hydraulic actuators, with the two control signals being the electric currents supplied to the actuators at the front and rear axles. Based on the developed dynamic model, the authors designed a PID controller and an LQR controller for the active antiroll bar system, aiming to reduce the vehicle body's roll angle. Simulation results in both the frequency and time domains clearly demonstrate the effectiveness of the active antiroll bar system with the designed controllers in improving vehicle roll stability under various operating conditions. Additionally, the study investigates the influence of speed on the vehicle handling characteristics under specific driving scenarios. The results also show that the active antiroll bar system performs effectively across a wide range of vehicle speeds from 0 to 200 km/h (up to 60% using an LQR controller and up to 80% using a PID controller), while maintaining the handling capability of the car.
