Design and experimental validation of control algorithm for vehicle hydraulic active stabilizer bar system

Abstract

This paper presents a novel active roll control algorithm for vehicle hydraulic active stabilizer bar system. The mechanical structure and control scheme of hydraulic active stabilizer bar system is detailed. The anti-roll torque controller is designed with “Proportional-Integral-Differential (PID) + feedforward” algorithm to calculate the total anti-roll torque. A lateral acceleration gain and roll rate damping are added into “PID + feedforward” controller, which can improve vehicle roll dynamic response. The torque distributor is introduced based on fuzzy–PID algorithm to distribute the anti-roll torque of front and rear stabilizer bar dynamically, which can improve vehicle yaw dynamics response. The actuator controller is used for realizing the closed-loop control of the actuators displacement and generating the accurate anti-roll torque. The hardware-in-the-loop simulation platform is established based on AutoBox and active stabilizer bar actuators. The hardware-in-the-loop experiment is carried out under typical maneuvers. Experimental results show that the proposed control algorithm improves the vehicle roll and yaw dynamics response, which can enhance the vehicle roll stability, yaw stability, and ride comfort.

Enhancing the Stability and Safety of Vehicle When Steering by Using the Active Stabilizer Bar

“…In [25], Muniandy et al used an intelligent control method with the Fuzzy PI-PD algorithm to determine the value of these parameters. is combination was also shown in [26] by Dawei et al e di erence between simulation and experimental results is not large. In [27], Khalil et al used the fuzzy logic algorithm to determine the parameters for the controller of the electronic stabilizer bar.…”

Preventing rollover phenomenon with an active anti-roll bar system using electro-hydraulic actuators: A full car model

“…Table 3 shows clearly the decrease of the transfer function magnitude at 1rad/s. It is important to notice that for the AARB system with steering disturbance, the frequency range of interest is lower than 4rad/s [4,12,21]. Thus, the evaluation criteria have decreased significantly when compared to the car using the passive suspension system.…”

A complex rollover dynamics model with active stabilizer bar controlled by the fuzzy algorithm

“…The pressure of the liquid inside the system is generated by the axial piston pump ( Hilaire et al., 2006 ). In ( Dawei et al., 2018 ), Dawei, et al. used the PID algorithm to control the operation of the stabilizer bar.…”
