This paper is focused on reliable fuzzy H∞ controller design for active suspension systems with actuator delay and fault. Takagi-Sugeno (T-S) fuzzy model approach is adapted in the study with consideration of the sprung and unsprung masses variation, the actuator delay and fault, and other suspension performances. By utilizing parallel-distributed compensation scheme, a reliable fuzzy H∞ performance analysis criterion is derived for the proposed T-S fuzzy model. Then, a reliable fuzzy H∞ controller is designed such that the resulting T-S fuzzy system is reliable in the sense that it is asymptotically stable and has a prescribed H∞ performance under given constraints. The existence condition of the reliable fuzzy H∞ controller is obtained in terms of linear matrix inequalities Finally, a quarter-vehicle suspension model is used to demonstrate the effectiveness and potential of the proposed design techniques.
