摘　　要：利用控制力矩陀螺(CMG)实现敏捷姿态机动控制时,保证机动过程控制输出力矩快速响应的同时,还需要保证机动到位后有效隔离CMG的机械振动以实现高稳定度姿态控制。针对控制CMG主动隔振平台,将控制CMG外框角速度作为变参数,提出单支腿主动隔振平台控制器的一种基于线性变参数(LPV)控制设计实现方法,通过与其他主动隔振控制方法性能比较分析,所提方法在兼顾敏捷姿态机动期间和机动到位后对主动隔振平台不同的力学传递要求方面有更好的性能。When the control moment gyro(CMG)is used to achieve agile attitude maneuvering control,the mechanical CMG vibration should be effectively isolated after the maneuvering is in place to achieve high-stability attitude control,while the rapid response of the control output torque is ensured during the maneuvering.This paper presents a design of outrigger controller for CMG vibration isolation platform based on linear parameter varying(LPV),setting the angular velocity of the CMG outer frame as a variable parameter.A comparison with other active vibration isolation methods demonstrates better performance of the design in different mechanical transmission requirements for the vibration isolation platform during agile attitude maneuvering and after the maneuvering in place.
