|
Abstract:
使用行走式压电致动器驱动望远镜整体转向方案是目前空间引力波探测补偿呼吸角变化的主流方案，分析了行走式压电致动器的致动原理与驱动信号，研制了一种行走式压电致动器驱动系统，使用正弦波为驱动电压波形，利用差分原理减少传统驱动信号量。测试系统各模块输出能力以及在不同频率下行走式压电致动器时间–位移曲线，分析驱动过程的稳定性。并利用角转换机构的模拟补偿过程，满足±1？补偿行程内仍能获得良好的输出特性。
The use of walking piezoelectric actuator to drive the overall steering scheme of the telescope is the mainstream scheme to compensate for the change of breathing angle in space gravitational wave detection. The actuation principle and driving signal of the walking piezoelectric actuator are analyzed, and a driving system of the walking piezoelectric actuator is developed, which uses sinusoidal waveforms as the driving voltage waveforms, and reduces the amount of the traditional driving signals by utilizing the differential principle. The output capacity of each module of the system and the time-displacement curve of the walking piezoelectric actuator at different frequencies are tested to analyze the stability of the driving process. And using the analog compensation process of the angular conversion mechanism to meet the ±1？ compensation stroke can still obtain good output characteristics.
