Abstract. In this study, we address the problem of fault-tolerant control (FTC) H_(∞ ) of active vehicle suspension systems (ASS) systems with time delays and actuator fault. The H_(∞ )performance criterion is employed to assess ride comfort, allowing for the consideration of general road disturbances. A method for designing the controller established on Linear Matrix Inequalities (LMIs) has been suggested to handle actuator faults represented by a scaling factor. The control design guarantees the asymptotic stability of the system, mitigates the effects of actuator malfunctions, and maintains H_(∞ )performance although in presence of defective actuators. The effecency and robustness of the proposed approach are demonstrated through simulations and comparative analysis.
