Autopilot Design of Single Channel Rolling Missile

For a single channel rolling missile,the autopilot structure was constructed in body coordinate system.By rolling transfer of coordinate system,the structure loop was transferred to quasi-body coordinate system and was simplified.Then the autopilot structure was designed in quasi-body coordinate system.It is notified that the cross couplings between the vertical and lateral motion exist in the autopilot loop of quasi-body coordinate system.To eliminate the cross couplings,decoupling control of autopilot loop was implemented by means of series compensation.Simulation results prove that the design method presented in this article is feasible.
