摘　　要：在航天器中的仪器及所载的精密设备，必须能跟随航天器的起飞、运行等低频运动，但对于航天器由于喷射燃料等原因产生的高频振动要能很好地隔离。对电磁永磁混合悬浮隔振装置建立了水平和竖直两平动自由度控制系统的物理及数学模型，利用传递函数，采用极点配置法对控制系统综合，对给定的控制指标进行计算机仿真，证明能较精确地满足控制要求。Precise instruments and devices used on aircrafts should follow low frequency motion as aircraft taking off and on normal fying; on the other hand, they should also isolate the high frequency motion caused by spurting fuel, etc. This paper studied a novel isolating method electromagnet and permanent magnet suspension isolation. After establishing the physical and mathematicn models concerning horizontal and vertical translation freedom degree, the paper proposed a pole placing method to design the control system. By computer simulation, it is indicated that the control system could meet the task well.
