摘　　要：针对导引头伺服装置的特点,推导了装置在搜索和跟踪工作模式下的输入输出特性,并重点分析了在这两种工作模式下,装置指令跟踪性能和扰动隔离性能之间的差异,指出了传统的只考虑陀螺稳定回路的系统隔离度指标确定与测试方法的局限性,同时提出了采用位置回路补偿陀螺随机漂移误差的方法。该研究为导引头伺服装置,以及其相关光电稳定跟踪装置的陀螺选型、控制系统设计及性能指标测试提供了参考和理论依据。According to characteristics of the seeker mechanism under searching and tracking mode,transfer functions between input and output were derived in detail,and distinction of the tracking performance and disturbance attenuating performance were analyzed completely.Moreover,the unfitness of the traditional methods to decide or test the index of the mechanism was also pointed out,which only related the capability of seeker servo mechanism to attenuate the movement disturbance of the missile body with the gyro stabilization control loop.A new method was proposed to reduce the random drift of gyros,which induced errors to the seeker mechanism control loop.Experiments validate the conclusions and researches,which can be contributed to the selection of gyros,control system design and performance testing of the seeker servo mechanism or related E-O tracking mechanism.
