摘要
针对目前激光跟踪测量技术中测量距离与跟踪控制参数的精确匹配问题,研制了一套基于距离自适应跟踪策略的远距离目标激光精密跟踪控制系统.根据不同距离处所标定的电机跟踪控制参数,构建了基于最小二乘法多项式拟合的距离自适应参数模型,获得了标定距离范围内与任意距离匹配的跟踪控制参数,从而实现了远距离目标的稳定跟踪.对所研制系统装置进行了跟踪控制参数标定实验、圆轨迹跟踪性能验证实验及目标轨迹坐标测量实验.实验结果表明,所设计跟踪系统可实现50 m范围内运动目标的稳定跟踪测量,且跟踪速度均不低于500 mm/s,可应用于远距离动态目标的精密跟踪测量.
Abstract
Aiming at the problem of accurate matching between measuring distance and tracking control parameters in current laser tracking and measurement technology,a laser precision tracking and control system based on range adaptive tracking strategy is developed.According to the motor tracking control parameters calibrated at different distances,the range adaptive parameter model based on least square polynomial fitting is constructed,and the tracking control parameters matching with any distance within the calibration distance range are obtained,and the stable tracking of long-distance targets is realized.Tracking control parameter calibration experiments,circular track tracking performance verification experiments and target track coordinate measurement experiments are carried out for the developed system.The experimental results show that the designed tracking system can stably track and measure the moving target with the range of 50 m,with not less than 500 mm/s tracking speed,and it can be applied to the precision tracking and measurement of long-distance dynamic targets.
