Abstract

In this paper, a hierarchical control logic for 2-channel hydraulic active roll control (ARC) system, which includes vehicle level control and actuator level control is proposed. Vehicle level control consists of anti-roll torque controller and anti-roll torque distributor. The anti-roll torque controller is designed with 'PID+feedforward' algorithm to calculate the total anti-roll moment. The anti-roll torque distributor is devised based on fuzzy control method to implement an anti-roll moment allocation between the front and rear stabilizer bar. Actuator level control is designed based on pressure and displacement respectively. The contrastive analysis of the two proposed actuator control method is presented. The hardware-in-the-loop (HIL) test platform is proposed to evaluate the performance of the devised control algorithm. The HIL simulation result illustrates that actuator displacement control could generate a relatively accurate anti-roll moment, and the vehicle roll stability, yaw stability can be enhanced by the proposed ARC control method.
