Pole assignment method with state constraints for missile three-loop autopilot design

The three-loop autopilot is transformed into states space model, and the feasibility of presupposition of some nuisance parameter is proved. A new pole assignment method is studied. Considering the actuator state feedback constraints, search methods are used to find the additional poles introduced by actuator. The design results show that, with the new method, all the poles of the system can be assigned to the desired place.
