摘　　要：为了提高滚仰式半捷联光电稳定平台的视线指向测量精度,提出一种稳定平台误差建模与参数标定的方法。针对滚仰式导引头的结构特点,分析了稳定平台的主要误差来源,利用坐标变换法和泰勒公式建立了失调角的线性误差模型,设计了通过补偿失调角误差提高稳定平台的视线指向测量精度方法。针对稳定平台误差参数标定问题,利用最小二乘法设计了误差参数标定方法。仿真结果表明:误差参数标定方法可以有效标定误差参数,通过失调角线性误差模型补偿失调角误差的方法可以显著提高稳定平台视线指向测量精度。In order to improve the pointing accuracy of roll-pitch semi-strapdown photo-electricity stabilized platform,a method for error modeling and parameter calibration of stabilized platform is proposed.Based on the mechanical structure characteristics of the roll-pitch seeker,the main error sources of the stabilized platform are analyzed.Established the linear error model of the misalignment angle by using the coordinate transformation method and Taylor formula,and designed a method to improve the line-of-sight measurement accuracy of the stable platform by compensating the misalignment angle error.The least square method is used to design the calibration method of error parameters.The simulation results show that the error parameter calibration method can effectively calibrate the error parameters,and the method of compensating the misalignment angle error through the misalignment angle linear error model can significantly improve the line of sight pointing measurement accuracy of the stabilized platform.
