针对倾斜转向（BTT）导弹自动驾驶仪，提出了一种由基于扰动观测器的鲁棒反馈和前馈补偿组成的解耦控制策略。对于三个通道中的每一个，由非线性耦合和外部干扰组成的集总干扰由干扰观测器估计，然后进行前馈补偿。设计了三个分布式鲁棒状态反馈控制器，分别稳定三个通道的其余线性部分。仿真研究证明了该方法的有效性。
A decoupling control strategy consisting of robust feedback and feedforward compensation based on disturbance-observers is proposed for bank-to-turn (BTT) missile autopilot. For each of the three channels, the lumped disturbances, which consist of nonlinear couplings and external disturbances, are estimated by a disturbance observer and then feedforward compensated. Three distributed robust state feedback controllers are designed to stabilize the rest linear parts of three channels, respectively. Simulation studies demonstrate the effectiveness of the proposed method.
