摘　　要：建立了1/2车四自由度油气悬架的T-S模糊模型。采用并行分布补偿器(PDC)结构,基于线性矩阵不等式处理方法,提出了模糊保性能控制方案,导出最优保性能控制律,针对含有参数不确定的油气悬架系统进行了仿真与实车道路试验。结果表明,与被动油气悬架相比,采用了保性能控制的油气悬架在减少振动、提高车辆行驶平顺性方面性能更优。A T-S fuzzy model of four Degree-of-freedom hydro-pneumatic suspension of a half-vehicle is established.Based on the parallel-distributed compensator （PDC）structure and linear matrix inequality （LMI）,this paper presents a fussy guaranteed performance control scheme for the model,derives the optimal guaranteed performance control law,and completes simulation and road tests with respect to the hydro-pneumatic suspension system with uncertain parameters.The results indicate that the hydro-pneumatic suspension adopting guaranteed performance control possesses even better performance than the passive hydro-pneumatic suspension in the respect of vibration reduction and improvement of driving smoothness of the vehicle.
