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.
In order to improve the vibration control quality of large axial acceleration and deceleration system with uncertain system structural parameters, an adaptive boundary control method based on Lyapunov theory, adaptive control technique and curve acceleration-deceleration method is proposed to suppress the structural vibration offset The designed adaptive control can avoid the control spillover effect and compensate the uncertainty of the system parameters, and ensure the uniform boundedness of the closed-loop system and the closed-loop state.The simulation results show that the designed adaptive boundary-control algorithm can be effective Suppression of structural vibration offset.
