摘　　要：研究旋转飞行器的解耦控制问题.考虑飞行过程中耦合对象系统的时变性,采用串联解耦网络对开环系统进行近似解耦,并采用模糊PID控制对闭环系统进行设计,实现了纵向和侧向通道之间的稳态解耦.仿真算例表明,该方法有效消除了旋转飞行器纵、侧向通道之间的耦合效应,在飞行状态时变的情况下能够获得良好的动态性能.This work studies on decouple control of the rolling aircraft. Considering the time-varying property of the couple system, a new decoupling method combining the series decoupling and fuzzy control was proposed. The series decoupling compensation net was employed to achieve approximately decoupling solution of open-loop system, and the structure of close＆loop system of parameter selftuning fuzzy PID controller was designed. Simulation and result analysis show that this method can effectively eliminate the steady coupling of the longitudinal and lateral channels of rolling aircraft, and can achieve good dynamic performance when the flight status is changed.
