| 摘要: |
| 针对高超声速飞行器倾侧转弯过程中俯仰、偏航和滚动通道间的强烈耦合，提出一种耦合控制策略。针对高超声速飞行器快时变、非线性和强不确定性的控制问题，基于解析形式的非线性最优预测控制方法，采用分层设计思想设计了飞行器姿态控制系统，可较好满足高超声速飞行器的快速性要求；在分析了倾侧转弯飞行控制过程的主要影响因素及其影响规律的基础上，提出一种“降低攻角—快速滚转—拉起攻角”的耦合控制策略。对该控制策略对于高超声速飞行器的适用性进行了仿真分析，结果表明：所提耦合控制策略有效降低了偏航通道的控制需求，降低了倾侧转弯控制过程的失控风险，提高了控制系统的可靠性。 |

| Abstract: |
| A coupling control strategy was proposed for the BTT (bank to turn) flight phase of hypersonic vehicle, according to the strong coupling among the channels of pitch, yaw, and rolling. Based on the nonlinear generable predictive control method, a hierarchy-structured predictive controller was designed and analyzed for rotation motion dynamics of a generic hypersonic vehicle, which has the characteristics of fast variability, high nonlinearity, and uncertain parameters. After analyzing the main influence factors and their effect laws during the BTT flight phase, a coupling control strategy called “decrease angle of attack—rolling fast—increase the angle of attack again” was proposed. Simulation studies were conducted to investigate the feasibility of the proposed control strategy for the hypersonic vehicle. The simulation results demonstrate that the proposed control strategy lowers the control requirement of yaw channel, lowers the probability of being out of control in the BTT flight phase, and increases the reliability of the control system. |
