Abstract：For the purpose of improving the vehicle roll stability and anti-rollover capability，a nonlinear control method for antiroll active hydraulically interconnected suspension (HIS) is developed with consideration of actuator dynamics. Firstly，the dynamics model and the liquid continuity equations of HIS are established, the nonlinear controller which is aimed at alleviating the roll angle therefore to improve the antiroll performance is completed based backstepping algorithm. Then，an objective function is constructed in order to ensure a smooth transition and desired-fixed value tracking for roll angle. Finally ,a simulation is carried out on the condition of step steering to validated the effectiveness of the control system, the result shows that the method succeeds in controlling body rolling posture and decreasing the load transfer ratio, and thus improves the antiroll performance and rollover limit, moreover, antiroll active HIS control system can also effectively enhance the suspension deflection and wheel load holding performance.
