| 摘 要： | 针对离心-振动试验系统的振动位移跟踪控制存在参数不确定性和干扰的问题,提出一种基于二阶滑模的振动位移跟踪控制方法。该方法基于高阶滑模控制基本原理,通过建立离心-振动复合试验系统数学模型,利用李雅普诺夫第二法设计出二阶滑模振动位移控制律。仿真结果表明：该方法在2 s内能够完成位移跟踪,跟踪准确度达到0.001 m,能够有效降低系统抖振,实现振动位移跟踪的精确定位,具有较高的控制精度和可靠性。

| Abstract: | With the second-order sliding mode control theory, a sliding mode vibration control method was presented for a centrifuge force-vibration test system to solve parameter variations and external disturbances. Firstly,the basic idea of the higher-order sliding mode control was introduced,then the mathematical model of centrifuge force-vibration test system was described and the control law of the second-order sliding mode vibration displacement was derived based on Lyapunov second method. The simulation results show that the method accomplishes positioning track within 2 s,and position track accuracy reaches 0.001 m. The method can effectively eliminate system chattering and achieve precise positioning for vibration tracking maneuver with high precision and reliability. |
