| 摘 要： | 考虑作动器中张紧轮质量的影响,研究轴向运动弦线和作动器所组成的耦合系统的横向振动控制。此系统被作动器分成受控和未控两部分,在频域内利用Green函数法求解出系统的响应,采用行波消去法设计出控制律。在初始条件和激励作用下,利用Durbin拉氏变换数值反演法将受控系统的振动响应转化到时域内,并利用Matlab进行数值仿真。算例结果表明:在脉冲激励和正弦激励作用下,系统振动在3秒内分别减小到0和未受控制时的1/5,验证了控制律的有效性。 |

| Abstract: | Vibration control of an axially moving string system consisting of a controlled span coupled to a tensioner is investigated by considering the influence of mass of the tension pulley.Transverse response of both the controlled and uncontrolled system is derived in the frequency domain by Green function method and the wave cancellation method is then employed to design the control law for ensuring the vibration reduction.The Durbin's numerical inversion of Laplace is employed to transform the vibration respon... |
