Autopilot Design with Two Degree of Freedom $H_{\infty}$ Control Method

2자유도 $H_{\infty}$제어기를 이용한 비행체 자동조종장치 설계

In this paper, we present a robust Two Degree of Freedom (TDF) $H_{\infty}$ controllers for a missile system. The feedback controller is designed to meet robust stability and disturbance rejection specifications while the prefilter is used to improve the robust model matching properties of the closed loop system. As the perturbed model, we use the normalized coprim factor perturbations. These controllers are designed using $H_{\infty}$ optimization procedures, and applied to a missile model via simulation.
