摘要： 提出了一种自适应高速脉冲式电磁光阀.由于电磁光阀存在较大的不确定性,为了在基本结构确定的情况下,通过调整驱动电流的波形参数,提高光阀的工作频率,采用了实验的方法,观测在多种可控参数取不同数值时光阀的工作状态,然后据此观测数据,利用遗传算法,设计具有自适应性的模糊控制系统.实验结果表明,该电磁光阀具有不影响光路特性、结构轻巧、使用寿命长、开关频率高和与之相应的足够大的开关孔径等优点.并已成功应用于三维激光扫描装置.

Abstract: This paper introduces an adaptive high-speed pulse electromagnetic light valve.Because of some uncertainty of electromagnetic light valves,in order to raise the frequency of the valve in certain basic structure by adjusting the parameters of drive current,we observed the status of the valve in various controllable parameters through experiments.Then,these data are used to design adaptive fuzzy control system by means of genetic algorithms.The advantages of the valve are no influence on the character of the light path,simple structure,long life,high frequency and relatively large switch calibre,etc.The valve is applied successfully in 3D laser scanning equipment.
