摘要
由于被测目标运动速度和加速度的不断提高,致使光电经纬仪跟踪的动态误差急剧增大;而现有的控制方法已逐渐无法满足控制精度的要求。为此,提出将预测滤波算法应用于光学测量的跟踪伺服系统,采用KALMAN滤波技术在MATLAB仿真及电视跟踪系统中实测,仿真及实测结果表明预测滤波算法可以较大幅度的减小跟踪误差,提高系统的跟踪精度。
With the increasing of the velocity and acceleration of the moving target, a large increasing of dynamic error of optoelectronic theodolite is produced. The existing control methods can not meet the requirement of tracking preci- sion. Therefore, the predictive filter method is applied to the optoeleetronic measurement tracking servo system. The system using Kalman predictive filter is simulated by Matlab and tested by television tracking system and results show that the predictive filter method can greatly decrease the tracking error and improve the tracking precision.
