| 摘 要： | 研究空空导弹快速响应优化问题,空空导弹大攻角飞行时,由于出现非对称涡及涡破裂现象,导致强烈的通道间耦合并呈现非线性特性,影响速度特性。为解决上述问题,设计了一种直接动态反馈补偿理论(Direct Dynamics Feedback Com-pensation,DDFC)控制策略的解耦控制器。首先建立了具有大攻角导弹耦合特性非线性数学模型,并直接动态反馈补偿理论给出了一种解耦控制策略,结合滑模变结构控制理论设计了解耦控制器。最后,对控制系统进行了数值仿真,仿真结果验证了改进方法的可行性。 |

| Abstract: | The strong coupling between channels and non-linear characteristics is caused by asymmetric vortex and vortex breakdown phenomenon under the high angle of the air to air missile.Firstly,a mathematical model of coupling characteristics of the missile was established in this paper,and a sliding mode decoupling control was given based on DDFC(Direct Dynamics Feedback Compensation).At last,the simulations show that the performance of decoupling and command tracking by this designed control system are quite good. |
| Keywords: | Air-to-air missile High angle of attack Decoupling DDFC |
