针对具有大加减速的轴向移动系统,为有效抑制结构振动和避免控制溢出问题,将鲁棒边界控制技术与Lyapunov直接法相结合,基于结构无限维模型设计鲁棒边界控制器对结构振动进行主动控制.使用符号函数处理未知扰动,提高了控制器系统鲁棒性,并对控制系统的稳定性和一致有界性进行了验证.仿真结果表明,所提出的鲁棒边界控制方法能有效抑制结构的振动.
For the axial movement system with large acceleration and deceleration, in order to effectively suppress the structural vibration and avoid the control overflow problem, the robust boundary control technique is combined with the Lyapunov direct method, and the robust boundary controller is designed based on the infinite dimensional model of the structure. Control.Using symbolic functions to deal with unknown disturbances, the robustness of the controller system is improved, and the stability and uniform boundedness of the control system are verified.The simulation results show that the proposed robust boundary control method can effectively suppress the structure The vibration.
