摘　　要：陀螺稳定平台广泛应用于机载光电等军用和监视设备中。本文提出一种抑制Stribeck摩擦来提高稳定平台稳定精度的解决方案。为分析此方法的性能,给出了分析模型,并通过对比试验验证了该方法的有效性。测试结果表明,此方法能够在不改变稳定平台硬件特性的前提下,将系统的稳定精度提高一倍。Gyro-stabilized platform is widely used in military reconnaissance and surveillance sys- tem, such as airborne electro-optical reconnaissance pod. A method of holding down Stribeck friction to improve the stability precision of gyro-stabilized platform is presented. Mathematical model for analysis is formulated to evaluate the performance of the presented approach. A contrast is given to test the effectiveness of the method. The experiment results show that the stability precision of gyro-stabilized platform is improved by 100% in the improved method without changing the hardware of the system
