雷达伺服系统的结构谐振由机械传动链柔性和负载惯量引起。结构谐振频率直接影响伺服系统的带宽、稳定性、快速响应及跟踪精度。所以,实际测量伺服系统的结构谐振频率,对伺服系统有关性能的整定具有实际的指导意义。基于结构谐振频率的定义,提出了一种工程上易于实现的结构谐振频率测量方法,通过仿真、分析计算和实验证明了该方法的可行性和有效性。

The structural resonance of radar servo system is caused by the flexure of mechanical drive link and load inertia.The structural resonance frequency influences capabilities of servo system,such as bandwidth,stability,quick response and tracking accuracy.It's important to the tuning of capabilities of servo system by measuring real structural resonance frequency.Based on the meaning of structural resonance frequency,a measuring method of structural resonance frequency is proposed which is easy achieved in pr...
