倾斜转弯技术是高超声速滑翔飞行器控制的一个重要发展方向。针对高超声速滑翔飞行器倾斜转弯技术开展研究。以平衡滑翔弹道为参考弹道,分析了转弯半径、下降高度、倾侧角等参数之间的关系,提出在设计高超声速滑翔飞行器制导控制指令时,应综合考虑不同高度速度下的控制能力约束。根据奇异摄动理论将动力学系统的受控状态变量分为快变量和慢变量两部分,运用轨迹线性化方法设计了控制系统。仿真结果表明,设计的控制器具有良好的控制性能,但随着高度的增加,控制指令应结合实际控制能力,以完成对飞行器的姿态控制。
Tilting turn technology is an important development direction of hypersonic gliding aircraft control. Aiming at hypersonic gliding aircraft tilt turning technology. Taking the balance gliding ballistic trajectory as the reference trajectory, the relationship between the parameters such as turning radius, descent height and tilting angle is analyzed. It is suggested that the constraints of control ability under different altitude velocities should be considered when designing the guidance control directive of hypersonic glide aircraft. According to the singular perturbation theory, the controlled state variables of dynamical system are divided into two parts, fast and slow. The trajectory linearization method is used to design the control system. The simulation results show that the designed controller has good control performance, but with the increase of height, the control instructions should be combined with the actual control ability to complete the attitude control of the aircraft.
