Abstract: According to the perturbation problem of system parameter and controller in active suspension, H2/generalized H2 optimal control method based on static output feedback was discussed. The existence condition and design approach of non-fragile controller were presented via a set of bilinear matrix inequalities. Taking half-car model as example, non-fragile active suspension was designed using suspension deflection, which demonstrated its robustness and non-fragility by analyzing it from frequency domain and time domain. Finally, real-time simulation experiment based on dSPACE was made to validate the proposed method.
