摘要
针对控制力矩陀螺(CMG)框架伺服系统带宽中的幅值和相位受到限制问题,提出一种前馈补偿方法;但是由于伺服系统中电流环调节系数对框架转速的敏感性,使得简单定值的PID调节参数很难在稳态静差和动态纹波两方面都将系统调节到最佳状态。采用模糊控制的方法并通过仿真和实验证明解决了调节参数需要随反馈速度变化的难题,补偿了前馈解决带宽问题的不足之处。
For the problem of amplitude and phase restricted in bandwidth of control moment gyroscope （CMG） gimbal servo system, proposed a method of feed forward to compensate the attenuation of amplitude and lag of phase. However, the sensitivity of adjusting coefficient to gimbal veloci- ty made simple parameter of PID difficult to reach the optimization when static difference and dynam- ic ripple to conflict in the current ring. And the paper adopted the fuzzy control to solve the difficult problem that adjusting coefficient changed with velocity feedback, to compensate lack of solution of bandwidth problem.
