基于参数空间法的BTT导弹自适应自动驾驶仪设计

Adaptive Autopilot Design for BTT Missile Based on Parameter Space Method

针对工程中出现的参数不确定性引起的系统性能下降,应用参数空间法设计了某型BTT导弹的模型参考自适应自动驾驶仪。首先根据参数空间法求取内回路控制器增益,充分保证系统的鲁棒性。再针对过载回路设计了模型参考自适应控制器,改善了局部非线性特性的响应,同时又增加了系统调节的快速性。最后,通过数字仿真表明这种设计方法的有效性。

For the falling system performance caused by parameter-uncertainty in project,this paper designed a model reference adaptive autopilot for a certain BTT missile based on the parameter space method.At first,the gain of inner-loop controller is obtained by the parameter space method which can keep the robustness of system.Then,the model reference adaptive controller is designed for acceleration-loop to improve the response of local nonlinearity property.At the same time,this method can also increase the rapidity of system for adjusting disturbance.Finally,the digital simulations are presented to verify the validity of this method.
