摘　　要：建立某直升机飞控系统俯仰串联舵机伺服系统的模型并进行仿真,重点研究了不同状态下该串联舵机伺服系统的动态行为及双通道间的均衡控制。研究结果已应用于某型直升机设计中,该仿真模型也可作为伺服回路的监控模型用于进行飞行中自检测,具有极高的工程应用价值。By modeling, simulation and analysis on the pitch serial actuator servo control system in helicopter, it was studied that how the servo control system behaved on various conditions and how the dual control systems worked balanced through an equalizer The results were applied to the design of the similar serial electric servo systems of one helicopter. The model can be treated as reference model of servo system for monitoring in-flight. It is beneficial to applications in practice.
