THE DECOUPLING CONTROL FORAIRCRAFT IN RAPID ROLL

The control problem for aircraft in rapid roll is analyzed. A 5-DOF modelis used to derive a decoupling control law of roll, pitch and sideslip angular velocitiesaccording to the nonlinear decoupling theory. The stability of the closed-loop system isdiscussed. A method to stabilize the whole system when some fixed dynamics areunstable is given. Simulations are perfonned.

飞机急滚运动的解耦控制

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。
