基于μ综合方法的空空导弹鲁棒驾驶仪设计

为了提高导弹驾驶仪的鲁棒性能，采用μ综合方法设计了算例空空导弹三通道的控制律.设计过程中考虑了控制对象的参数不确定性、未建模动态特性、外部扰动和通道间耦合等因素，解决了经典控制方法只能进行鲁棒性验证的问题.相对于其他鲁棒控制方法，μ综合方法还可以同时针对鲁棒稳定性和鲁棒性能进行设计.仿真结果表明，μ综合驾驶仪满足各项性能指标，具有良好的鲁棒性能.

Robust Autopilot Design for Air to air Missile Using μ Synthesis

In missile autopilot design process, parameter uncertainties, un modeled dynamics and external disturbances can be considered by using μ synthesis, so better robustness can be achieved, while using traditional classical controller, it can only do robustness validation. Compared to other robust control theory, both robust stability and robust performance can be designed by using μ synthesis. In this paper, the uncertainty and disturbance model were built, the three channels robust autopilot control law for an example missile was designed, including coupling effect of each channel. The simulations show that the control system meets the requirements of control performances and reaches good robustness.
