Modeling and Verification for a Three-Degree-of-Freedom Airborne Electro-Optical Tracking and Pointing Platform

根据三自由度机载光电跟瞄平台的仿真目的,将建模重点确定为三轴环架的动力学特性同时推导了环架动力学方程,应用比较检测方法校核了该方程;在Simulink?中完成了模型实现,通过校核纠正并改进了模型实现;论文最后采用可接受检验方法,验证了环架模型的正确性。在建模过程中结合V&V技术有效的保证了模型的可信度和正确性。

Firstly, according to the simulation aim of the three-degree-of-freedom airborne electro-optical tracking and pointing platform (ad. platform), the emphasis of modeling was laid on the kinetic characteristic of the three-axis gimbals system, which was the key component of the platform. Secondly, the gimbals system’s conceptual model in the form of kinetic equation was derived and verified through comparison testing. Then the model was realized on the Simulink? platform. Some coding errors and defects of the model realization were found and corrected through assertion testing and function testing. Finally, by applying acceptance testing, the similarity in the kinetic characteristic between the model and the physical platform was validated.
