摘要
针对具有系统结构参数不确定的大加减速轴向移动系统,为了提高其振动控制品质,结合Lyapunov理论、自适应控制技术和曲线加减速法设计自适应边界控制,用以抑制结构振动偏移量.所设计的自适应控制能避免控制溢出效应和补偿系统参数不确定性,并保证闭环系统的稳定性和闭环状态的一致有界性.仿真结果表明,所设计的自适应边界控制算法能有效抑制结构振动偏移量.
To improve the performance of the vibration control for an axially moving system under high ac-/deceleration with the system parametric uncertainty, an adaptive boundary controller is designed to suppress the vibration displacement of the system combining with the Lyapunov theory, the adaptive control technique and the -curve ac-/deceleration method. With the proposed adaptive boundary control, the control-spillover phenomenon can be avoided, and the system parameter uncertainty can be compensated. The stability of the closed-loop system is demonstrated and the uniform ultimate boundedness of the closed-loop signals is ensured. Simulation results show the effectiveness of the proposed adaptive boundary control method.
