摘要 磁悬浮支承应用于控制力矩陀螺具有高精度,长寿命的优点。高速转子的陀螺效应导致的失稳制约了其在CMG中的应用,尤其是章动造成的磁悬浮转子高速失稳问题。该文分析了由于陀螺效应产生的章动造成系统失稳的根本原因,提出了控制系统的解决方案。研究结果表明,章动失稳的主要原因是系统的相位延迟造成的,尤其对数字控制系统,相位延迟更为严重,使用简单交叉解耦控制不能解决问题,需要对现有的控制器进行优化才能保证系统在高速下的稳定性。 There are many merits to support control moment gyroscope(CMG) by using magnetic bearings, expect for the high rotor instability caused by the nutation under the situation of CMG unbalance. Analysis and simulation results show that the delay of phrase is the reason of the nutation underdamping especially in the digital control system. This paper puts forward a compensate method to diminish the original offset, which can guarantee a more robust stability.
