| 摘 要： | 为提高搭载于运动平台之光电跟踪系统控制回路的设计效率，以运动平台角扰动、目标运动特征以及系统跟踪误差指标为边界条件，基于系统建模和参数辨识，提出一种控制回路一体化设计方法，给出各环路控制器的解析表达及一组经验公式，并以某半实物仿真系统进行验证。在等效正弦125sin(0.4t) (mrad)角扰动环境下，对正弦输入200sin(t)/3 （mrad）的跟踪误差峰值不大于0.5 mrad，满足均方误差小于0.5 mrad的指标要求，表明该控制回路一体化设计方法的有效性。

| Abstract: | In order to improve the design efficiency of control loop in optoelectronic tracking system that fixed on mobile base, considering the angular disturbance of the moving platform,the target movement and tracking precision of system, based on system experimental modeling and parameter identification, an integrated design method of control loop was put forward, every controllers expression and a set of empirical formula were also provided.Additional, a semi physical simulation system was verified.The maximum tracking error of sine input 2000sin(t)/3 mrad with equal disturbance 125sin(0.4t) mrad is less than 0.5 mrad，which can satisfy the root mean square requirement for 0.5 mrad. The certain simulated test result of this hardware in loop tracking test proves the validity of integrated design method. |
