A Spin Missile Autopilot Designed Using Feedback Linearization

Dynamic model of a spin missile was established in pseudo body coordinates.A three axes autopilot based on dynamic feedback linearization control was developed for it.The system was divided into"fast"and"slow" subsystems through time scale separate.Controllers was designed respectively.The instable zero dynamics was cancelled and de- couple coutrol in pseudo body coordinates was archived.Numerical simulations showed that this autopilot is of good performance and robustness.
