摘　　要：极点配置方法在三回路驾驶仪设计中应用较广,针对开环截止频率这一关键参数的设计约束较为模糊。通过建立控制增益、闭环极点与系统开环截止频率的解析关系,将控制系统设计问题转化为开环截止频率的合理选择。结合鸭式布局导弹工程设计经验,分别讨论了舵机带宽、舵偏角速率、闭环零点和控制增益极性对开环截止频率选取的约束准则和工程应用修正,通过典型条件验证了该准则的适用性。The pole assignment method is commonly used in the design of three-loop autopilot,and the constraints for the key parameter that the open-loop crossover frequency was blurred.By concluding the analytical relationship between control gains,the close-loop poles and the open-loop crossover frequency,the control system design problem is transformed into a judicious choice of the open-loop crossover frequency.Combined with engineering experience of the Canard layout missile,the constraint criteria and modified methods for the selection of the open-loop crossover frequency of the rudder bandwidth,the fin rate,the close-loop zeros and the gain polarity are discussed.The applicability of the criteria is verified in typical conditions.
