【摘要】 大型雷达伺服系统由于传动机构的弹性变形而产生机械谐振,按经典理论设计此类系统,机械谐振很难克服。本文提出了一种基于现代控制理论的全状态反馈及观测器理论的新的设计方案,并以某实际的大型雷达伺服系统进行了计算机仿真。结果表明,本文提出的方案是可行的,较好地克服了机械谐振,从而大大提高了系统的快速性和抗风扰能力。同时,这种方案容易实现,所需增添的设备很少。更多还原

【Abstract】 Mechanical resonance usually occurs in a large-scale radar control system.It isdifficult to overcome the resonance by method based on classical control theory.Inthis paper,a new design method based on modern control theory and observer the-ory is presented,and is used in designing a practical large-scale radar control sys-tem.The results of simulation show that the mechanical resonance can be over-comed by applying the method.In addition,the method offers a efficient way of im-proving tracing and anti-disturbance ability.更多还原
