航空时敏制导炸弹滚转通道控制器设计

摘要航空时敏制导炸弹从与载机分离之后的飞行过程中，由于俯仰、偏航和滚转通道会有不同程度的耦合，故而制导炸弹控制系统设计一般采用首先单独设计各通道控制器，然后设计解耦回路的方法。本文基于经典控制理论，研究和设计了航空时敏制导炸弹滚转通道的控制器，通过时域和频域条件的分析，验证了所设计控制器的各项性能。在此基础上，进行了制导炸弹飞行全过程的751自由度弹道仿真，验证了本文所设计控制器参数的合理性，达到了预期设计要求。19806
除此之外，航空时敏制导炸弹在大空域、非线性条件下飞行时，随着高度和马赫数的变化，弹体的气动参数会有很大变化，传统的控制器在全弹道段会受到不同程度的干扰而导致制导精度下降。因此，本文最后提出了基于增益调度法的控制器设计方法，为提高控制器精度，进一步优化控制器设计提供了理论基础。

Title       Roll Channel Controller Design of Airborne
              Time-critical Guided Bomb
Abstract
During the flight of airborne time-critical guided bomb after being separated from the aircraft, parameters of pitch, yaw and roll channel would be coupled usually, so the control system is usually designed independently for each channel followed by a decoupled channel. Based on classical controller system theory, this paper designed the controller system for roll channel of the airborne time-critical guided bomb, and the function of this system is tested and verified in time and frequency domain. Based on that, the six-degree ballistic simulation is conducted and simulation results have proved that the designed control system is reasonable and can meet the requirements of the whole system.
In addition, as aerodynamic parameters change widely when the guided bomb is flying in large and nonlinear space with the change of height and Ma. So the accuracy can be affected during the whole flight trajectory when using traditional controller. Therefore, at the end of this paper, a method of gain scheduling controller designing method is proposed, which can then effectively improve the accuracy and provide a theoretical basis for further controller optimization.
Keywords：guided bomb，roll channel controller，gain scheduling method
