It connects opposite (left/right) wheels through short lever arms connected by a torsion spring. Heliyon, Elsevier 2019, 5 (6), pp.1 - 11. In a previous work, the authors proposed an H ∞ controller for this system. S331_170 S331_172. 60 mm either on one side or as an aggregate on both sides. Simulation results in both frequency and time domains are provided to compare two different cases: passive anti-roll bars and H ∞ active anti-roll bars. The part numbers in the assembly image relate to the product number in the table. The control signal is the current entering the electronic servo-valve and the output is the force generated by the hydraulic actuator. The Genetic Algorithms method was used to handle the vehicle roll stability and the energy consumption of the actuators via the Pareto optimality. When cornering, the lateral inclination (roll) of the SUV’s body is significantly reduced by the active anti-roll bars. McLaren's Proactive Chassis Control Suspension Is the Anti Anti-Roll Bar. This thesis investigates the potential of implementing active anti-roll bars in a passenger vehicle with the purpose of increasing customer value. The control signals are the torques generated by the actuators at the front and rear axles.
