摘要
为提高飞机的过失速机动能力 ,参考 X-3 1 A飞机的飞行控制系统模型 ,对非线性因素如气动力、陀螺惯性耦合以及重力影响进行补偿后 ,按飞行品质要求采用隐模型跟踪法设计了某机的反馈控制器。计算仿真表明 ,该控制器能够较好地发挥飞机的操纵潜力 ,可使飞机在获得较好的过失速机动能力的同时具有较为满意的飞行品质。引入推力矢量控制 ,可增加飞机的操纵效能 。
To improve the post stall maneuverability of aircraft, by reference to the flight control system design philosophy of X 31A, compensating the non linear factors such as aerodynamics, motional coupling and inertial coupling, a controller was constructed by the implicit model following technique for satisfactory flying qualities. The simulation results have been shown that this controller can take full advantage of aircraft control potential and improve the post stall maneuverability with satisfactory flying qualities. The control effectiveness for aircraft can increase by using the thrust vector.
