中文摘要:
      目的 对在轨大型空间柔性桁架天线结构振动进行主动控制及作动器位置优化。 方法 采用线性二次型最优控制算法对天线结构进行振动抑制,以系统能量和控制能量的和作为优化性能指标,利用遗传算法对作动器的位置进行优化。结果 在优化配置的两个作动器控制作用下,受到激扰的天线结构振动便在10 s内得到良好得抑制,振动幅值减小了一个量级。 结论 适当地增加作动器数目,恰当地配置作动器的位置能有效抑制柔性天线结构的振动。
英文摘要:
      Objective To conduct active control on the vibration of large space flexible truss antenna structure and optimize the position of actuator. Methods A linear quadratic optimal control algorithm was used to suppress the vibration of the antenna structure. The sum of system energy and control energy was taken as the optimization performance index. The position of actuator was optimized with genetic algorithm. Results The vibration of the antenna structure was well suppressed in 10 s and the vibration amplitude was reduced by one order of magnitude when being controlled by two optimal actuators. Conclusion Appropriately increasing the number of actuators and properly configuring the position of the actuator can effectively suppress the vibration of flexible antenna structure.
