摘要
为了提高动基座光电平台视轴稳定精度,必须提高伺服系统对扰动力矩抑制的能力。针对这种情况,提出了在伺服系统中引入加速度反馈闭环来抑制扰动力矩。仿真、分析结果表明,加速度反馈闭环的引入有效增强了动基座光电平台伺服系统的力矩刚度,极大的抑制了扰动力矩,将动基座光电平台视轴稳定精度由177.8 rad提高至8.5 rad。
To improve the stabilization of line of sight（LOS）,high dynamic stiffness is required in the servo system of moving base Electro-Optical Platform.Therefore,an acceleration feedback loop is presented for classical servo system as an inner loop.The simulation results and analysis show that the acceleration feedback loop enhances the dynamic stiffness of servo system of Electro-Optical Platform and improves stabilization of LOS from 177.9 rad to 8.5 rad under the condition of disturbances.
