Missile Autopilot Design Using a Robust Asymptotic Tracking Controller

A robust asymptotic output command tracking controller is proposed to control the longitudinal motion of a missile nonlinear model. The nonlinear model is linearized and the equilibrium points are considered uncertain parameters. The proposed robust controller operates at various flight conditions. The derivation of the PI type dynamic controller parameters is based on a robust stabilizability algorithm appropriately enriched by a metaheuristic search algorithm. Simulation results to the nonlinear model illustrates the effectiveness of the proposed robust controller at various flight conditions.
