摘　　要：随着天线口径的增大,对于伺服系统的要求也越来越高。大口径天线的刚性和结构谐振频率降低,导致伺服系统的动态滞后加大,甚至可能造成雷达丢失目标。通过对新测量船伺服控制系统的分析,建立了伺服系统的控制模型,并将智能积分器应用到位置控制环路中。仿真结果表明,智能积分器能够有效的减小超调量,加快调节速度,取得了较好的控制效果。Along with improvement of capability of the precision measurement radar, the servo system with more high capability is needed. A large antenna reduces rigidity and structural resonance frequency of antenna system, and it is even possible to make radar lose the target. Based on analyzing Ship-borne servo system, the model of servo system has been set up and intelligent integral has been applied in the Position Control Loop. The result of simulation shows that this method can decrease overshoot of the servo system and improve the quickness of the servo system.
