摘　　要：针对主动空气悬架这种时变、非线性复杂系统,以空气悬架客车1/4模型为控制对象,提出了模糊自适应滑模控制策略(FASMC),其中模糊自适应系统用来处理空气悬架系统的非线性和参数不确定性,并以最优控制的理想空气悬架作为参考模型。仿真试验表明,所提出的控制器能够有效降低车身振动幅度、提高车辆的可操纵性。Due to nonlinearity and parameter uncertainty in air suspension, it is difficult to control the suspension system. To achieve a desired performance, a fuzzy adaptive sliding mode controller （FASMC） has been designed to improve the passenger comfort and manipulability of the vehicle, in which the fuzzy adaptive system is used to deal with the nonlinearity and uncertainty of the air suspension. A normal linear suspension model with an optimal state feedback control is designed as the reference model. The simulation results show that this control scheme is effective in the vibration isolation of the vehicle body.
