For practical application, this paper presented a fuzzy static output feedback controller design approach for vehicle electro-hydraulic active suspensions. Takagi-Sugeno(T-S) fuzzy modeling was applied for approximating the dynamic nonlinear active suspension model.Three main performance requirements should be considered in designing suspension, ride comfort, handing stability and suspension deflection, this paper took the vertical acceleration of the car body as H₂ performance, and suspension deflection and tyre deflection as the H_∞ performance.NSGA_2 was atilized for searching the feedback gain matrix, the H₂ and H_∞ norm were acquired via solving LMI. The comparison of the simulation results between active suspension and passive suspension in MATLAB/simulink shows that the three main performances of active suspension are better.
