Autopilot strategies of guided projectiles for terminal guidance

The goal of this article is threefold: (1) Present a thorough model of a generic fin-guided projectile involving the 6DoF nonlinear dynamics, equilibrium point computation, Linear Parameter Varying (LPV) modeling & stability analysis concepts (2) Investigate various structures of low complexity closed loop feedback controllers that could be potentially applied to fin-guided projectile autopilots. (3) Investigate several crucial modeling issues relevant to autopilot design such as state space transformations which avoid output feedback in favor of state feedback, actuator model incorporation, etc. Simulation results demonstrate the performance and the complexity aspects of the proposed control algorithms.
