针对具有执行器时滞和故障的主动悬架系统，研究了可靠模糊H ∞控制器的设计问题。在这项研究中，Takagi-Sugeno（T-S）模糊模型的方法是适应考虑簧上和簧下质量的变化，致动器延迟和故障，以及其他悬架性能。利用并行分布式补偿方案，一个可靠的模糊H ∞性能分析准则，提出的T-S模糊模型。然后，一个可靠的模糊H ∞控制器的设计，使得所得到的T-S模糊系统是可靠的，在这个意义上，它是渐近稳定的，并具有给定的约束下的H ∞性能。以线性矩阵不等式（LMI）的形式给出了可靠模糊H ∞控制器的存在条件。最后，以四分之一车辆悬架模型为例，验证了所提设计方法的有效性和潜力。
This paper is focused on reliable fuzzy H-infinity controller design for active suspension systems with actuator delay and fault. The Takagi-Sugeno (T-S) fuzzy model approach is adapted in this study with the consideration of the sprung and the unsprung mass variation, the actuator delay and fault, and other suspension performances. By the utilization of the parallel-distributed compensation scheme, a reliable fuzzy H-infinity performance analysis criterion is derived for the proposed T-S fuzzy model. Then, a reliable fuzzy H-infinity controller is designed such that the resulting T-S fuzzy system is reliable in the sense that it is asymptotically stable and has the prescribed H-infinity performance under given constraints. The existence condition of the reliable fuzzy H-infinity controller is obtained in terms of linear matrix inequalities (LMIs) Finally, a quarter-vehicle suspension model is used to demonstrate the effectiveness and potential of the proposed design techniques.
