摘　　要：运用变结构控制理论,采用指数趋近律对张紧臂的角位移进行控制,从而达到控制轴向运动弦线横向振动的目的.利用Matlab进行数值仿真,验证了所提控制力的有效性.The transverse vibration of an axially moving string coupled to an actuator is investigated in this paper. The variable structure control theory and exponentially reaching law are employed to design the control law. Reducing the angle displacement of the tensioner arm by the control law, the trans- verse vibration of the axially moving string can be controlled. Finally, numerical simulation is made via Matlab to verify the efficiencv of the control.
