一种光电跟踪仪的单杆数据处理方法

A processing method of joystick data in opto-electronic tracker

光电跟踪仪在手动工作模式下,伺服控制系统根据单杆量及位置步进指令对瞄线方位、俯仰方向进行控制。单杆数据的处理直接影响系统的跟踪性能。本方法利用了传统设备已具备的单杆数据接口,不增加设备硬件的复杂性,同时不影系统的其它性能;本方法依据系统特性设计了死区消除、数据归一化处理、低通滤波器和非线性处理,保证了系统工作的稳定性,使得光电跟踪仪单杆的操纵性能得到了彻底提升。

When the opto-electronic tracker is in the mode of manual-working, the servo-control system controls the aiming-line according to the data of joystick, so the processing of the data is critical to the system. This method uses the interface that the traditional equipment already has, so it does not increase the complexity of the hardware, and does not affect the other performance of the system. Eliminating dead zone, data normalization, low pass filter and nonlinear processing are designed according to the system characteristics,which guarantee the stability of the system, and the maneuverability of the joystick is improved.
