| 摘 要： | 为了消除惯性平台在导弹飞行过程中受到的不平衡力矩对其稳定性和跟踪精度的影响，提出了惯性平台不平衡力矩的测试和补偿方法.在得出平台内外框架静平衡条件的基础上，采用多个称重传感器对内外框架进行测试，得到每个框架不平衡力矩值，从而推导出在弹体运动的动态环境下内外框不平衡力矩的算式.根据不平衡力矩测试结果和算式，建立了基于不平衡力矩补偿的惯性平台内框控制模型.通过MATLAB/Adams对该模型进行联合仿真，结果表明了该补偿方法的有效性.

| Abstract: | A measurement and compensation method was proposed in order to eliminate the coupling effect on tracking accuracy and stabilizing capability due to unbalanced moment of inertial platform. The condition for static balancing of two axis gimbaled inertial platform was analyzed. Weight sensors were used to measure the static unbalance torque of inner and outer gimbal, then the calculation formulas of dynamic unbalanced moment during missile flight were derived. The simulation results of the built control model for inner gimbal in MATLAB/Adams show the effectiveness of the proposed compensation method for unbalanced moment. |
