直流力矩电机控制的动力陀螺稳定平台

摘要

在某对地攻击激光导引头中,采用了动力陀螺稳定平台；针对动力陀螺稳定平台对摩擦和噪声敏感的特点,使用了低摩擦力矩的直流力矩电机以及线性模拟驱动方式.考虑到力矩电机电磁参数、摩擦、导线干扰等不确定因素,对稳定平台设计了H∞鲁棒反馈控制器,并进行仿真分析和试验验证.结果表明,该稳定平台稳定性高,有较强的抗干扰能力,具有一定的有效性和优越性.%Dynamical gyro' s stable platform is used in an air-to-ground laser seeker. In order to reduce the infection of friction and yawp of the dynamical gyro' s stable platform, DC torque motor with linearity analog driving system is designed. Considering the unconfirmed factors of electromagnetic parameter, friction, lead-disturb of torque motor, the H∞ robust controller is designed. Simulation and experimentation indicate that the system is effective and ascendant such as stability and anti-jamming.
