摘要:

针对基本动态逆控制鲁棒性差的特点,设计了一种带有跟踪微分器的导弹增量动态逆过载控制律。首先建立了快慢两个回路的导弹过载控制模型,然后通过状态速率反馈,对快慢回路分别设计了增量式动态逆控制律,并进行了鲁棒性分析。最后通过引入快速跟踪微分器解决增量动态逆控制律中所需状态速率无法量测的问题。仿真结果表明,所设计的带有跟踪微分器的导弹增量动态逆控制律具有强鲁棒性。

Abstract:  

 Considering the weak robustness of dynamic inversion control, an incremental dynamic inversion control law for missiles with tracking differentiator is designed. Firstly, the overload control model of the missile is established, which can be divided into the fast loop and the slow loop. Then through the feedback of state rate, the incremental dynamic inversion control law is proposed for each loop, and its robustness is analyzed. During the design process, the fast tracking differentiator is introduced to solve the immeasurability problem of state rate. Simulation result shows that the proposed control law has excellent robustness.
