It deduced the body motion expression exactly from body coordinate system to quasi -body coordinate system, and introduced the scheme of double - channel and double servo to design the spinning projectile autopilot. It provided a decoupling control algorithm for the linear two input and two output system. The simulation results verified the quality of the scheme above introduced. Body state equation was suitable for the simulation and coupling analysis of double channel spinning projectile. The paper presented a new method for analysiing and designing the missile control system.
