某高超声速飞行器助推段纵向控制策略研究

为解决某高超声速飞行器助推段纵向控制的问题，以火箭助推垂直发射式飞行为对象，对其高超声速飞 行器助推段纵向控制策略进行研究。根据飞行器的飞行环境和自身结构，给出特性分析并剖析了控制难点，建立运 动参数时变模型，提出纵向姿态控制、增稳控制和迎角保护策略。分析结果表明：从稳定性和操纵性两方面与迎角 相比，俯仰角控制器具有更好操稳性，俯仰角速率指令内回路在助推段相比于阻尼内回路具有更好的鲁棒性。

Study on Longitudinal Control Strategy of Boost Phase for Certain Type Hypersonic Aircraft

In order to solve the longitudinal control problem of the boost section of certain type hypersonic aircraft, the longitudinal control strategy of the boost section of certain type hypersonic aircraft was studied based on the rocket-propelled vertical launch flight. According to the flight environment and the structure of the aircraft, the characteristics of the aircraft are analyzed and the control difficulties are analyzed. The time-varying model of motion parameters is established. The strategies of longitudinal attitude control, stabilization control and angle-of-attack protection are proposed. The analysis results show that the pitch angle controller has better stability than the angle of attack controller in terms of stability and maneuverability, and the pitch rate instruction inner loop has better robustness in boost phase than the damping inner loop.
