飞机急滚运动的解耦控制

THE DECOUPLING CONTROL FOR AIRPLANE IN RAPID ROLL

研究了飞机急滚运动的控制问题，采用５自由度横纵向耦合模型，应用非线性解耦理论，设计了关于滚转、俯仰和侧滑角的解耦控制体。讨论了闭环系统的稳定性，给出了当系统某些固定动态不稳定时，使系统实现稳定解耦的一个方法。最后进行了仿真研究。

The control problem for airplane in rapid roll is analyzed.A 5-DOF model is used to derive a decoupling control law of roll,pitch and sideslip angle according to the nonlinear decoupling theory.The stability of the closed loop system is discussed.A method to stabilize the whole svstem when some fixed dYnamics are unstable is given. At last,simulations are perfonned.
