High precision control based on ADRC used in gimbal system of MSCMG

  • 摘要: 针对非线性摩擦和外部随机扰动影响磁悬浮控制力矩陀螺(MSCMG, Magnetically Suspended Control Moment Gyroscope)框架系统角速率精度的问题,提出了一种基于自抗扰控制器(ADRC, Active Disturbance Rejection Controller)的高精度转速控制方法.通过三阶扩张状态观测器将框架系统负载力矩、非线性摩擦力矩及外部随机扰动力矩作为"总扰动"进行估计,并对该扰动力矩进行补偿.仿真及实验结果表明:基于自抗扰控制器的框架系统控制方法使框架转速精度和稳定度提高了50%以上,且具有抗干扰能力强和动态特性好的特点.
