摘要

针对大型卫星太阳能帆板(LSSP)振动主动控制器设计复杂、在轨扩展不易且容错性能有限等问题,提出一种适用于模块化结构的分布式振动控制方法。首先,根据LSSP的结构特点划分控制子模块,建立面向分布式控制的子模块动力学模型,并结合卡尔曼滤波算法设计各子模块线性二次最优振动控制器;然后,考虑各子模块之间的测量信息交互,提出应用于LSSP整体结构的分布式振动控制系统并分析闭环系统稳定性。最后,给出数值仿真算例以验证所提控制方法的有效性。结果表明,采用可扩展的分布式控制器,LSSP的振动能够得到有效抑制,且控制系统的容错性能良好。

Abstract

To deal with the issues such as complex design, difficult on-orbit expansion, and limited fault-tolerance in active controller of vibration of Large Satellite Solar Panels (LSSP), a distributed vibration control approach, which is suitable for the modular structure, is proposed in this paper. According to the structure characteristics of the panel, the LSSP is firstly divided into different units for control system design, and the dynamic model of each unit oriented towards distributed control is developed. The linear quadratic vibration controller of each unit is then designed using the Kalman filter algorithm. Considering the communication of the measured output of each unit, the final distributed vibration control system applied to the whole LSSP is proposed, and stability of the closed-loop system is analyzed. Simulations are finally conducted to verify the validity of the proposed controllers, and the results demonstrate that scalable distributed controllers can achieve vibration suppression for LSSP, and can provide good fault tolerance.
