| 摘 要： | 航空遥感用惯性稳定平台承载重量较大的成像载荷,系统相对复杂,耦合明显。根据航空遥感用三轴惯性稳定平台的结构特点,应用矢量叠加原理推导了平台环架运动学方程,建立了欧拉动力学模型,并分析了基座运动情况下各环架间的动力学耦合误差。仿真结果表明,基座对平台环架耦合较大,环架交叉耦合相对较小,且在外界干扰下基座及环架间的耦合加强。研究结果为稳定平台控制系统设计提供了依据。

| Abstract: | The inertial stabilized platform for aerial remote sensing can be used to carry heavy imaging load.This system is complex and the coupling is strong.Based on its configuration feature,the gimbal kinematics equations are established by adopting direction cosine matrix and vector superposition principle.Then the dynamics model is achieved on the basis of Euler equation.The dynamics coupling error of every gimbal is analyzed under the situation of base moving.Simulation result shows that the coupling between g... |
