| 摘 要： | 分析一种音圈电机驱动的快速控制反射镜(FSM)的机械结构,由此建立其数学模型。依据模型,以不完全微分PID控制算法来消除结构谐振的不稳定影响,采用线性功率放大驱动方式,可使控制带宽超过其结构谐振频率,实现高带宽控制。实验表明,该方法应用于结构谐振频率分别为90Hz和20Hz的两种快速控制反射镜,系统的抑制带宽能分别达到315Hz和240Hz,而且该方法简单可行,通用性强。

| Abstract: | A mechanical structure for fast-steering mirror (FSM) driven by voice coil motor (VCM) is analyzed and its mathematical model is established from the analysis. Relying on the model, the unstable influence of the structure resonance is eliminated with an incomplete differential PID control algorithm. The control bandwidth can surpass its structure resonance frequency and wide bandwidth control can be realized through applying linear power amplifier. The experiments show that when the method is applied to two kinds of fast-steering mirrors with structure resonance frequencies as 90Hz and 20Hz respectively, the rejection bandwidth of the system have attained 315Hz and 240Hz respectively. |
