自动换梭织机投梭侧板振动的主动控制

Active Vibration Control for the Picking Plate of Shuttle Loom Using Modern Control Theory

应用现代控制理论对自动换梭织机投按侧板振动的主动控制进行了研究，为振动主动控制的可行性提供了理论依据。建立并分析了投梭侧板的弹性体模型和控制系统的状态方程，提出了本系统能控性的系统等价理论。对可控程度问题进行了详细的研究，计算了控制点的最佳位置，讨论分析了控制点个敌对连续系统的影响。

We have studied the feasibility of active vibration control of shuttle loom by using modern control theory and establishing the state-variable equation of the nexible beam and picking plate system. An equivalent theorem for the controllability of the system is deduced and the optimal control point is determined. The effect of the numbers,of control points in continuous system is also discussed.
