| 摘 要： | 对飞机液压能源管路系统的振动问题进行了探讨.提出一种基于振动主动控制(VAC)技术对飞机液压能源管路系统进行消振的方法,在手段上采用压电/压电致伸技术,以压电陶瓷(PZT)作为作动器,具有驱动力大、响应频率高和体积小等优点;控制方法上采用参数寻优的控制策略,它能始终能根据外界干扰因素的变化来调整控制参数.经过理论分析和仿真验证,证明其具有良好的自适应性和鲁棒性,在变转速和变负载情况下始终能保持最佳的消振效果.

| Abstract: | The vibrations problem of fluid power supply and piping systems in aircraft is discussed,and presented a vibration active control method to reduce the vibrations of fluid power supply and piping systems. The multi-layer PZT is taken as the driver which is of characteristics of large force output, high frequency bandwith and small volume. The auto optimum control method is adopted, which can adjust control parameters at any time to aganist the disturbance.The simulation and experiment result prove that the scheme is efficient. All of the work is benefit to the vibration control in hydraulic system. |
