Design of autopilot for Aerodynamic/Reaction-jet Multiple control missile using variable structure control

A switch scheme of reaction-jet/aerodynamic multi-control missile using pose controlled pulse-engine is present. In order to increase response speed of autopilot and reducing the coupling form Reaction-jet to aerohelm, in the last stage of attacking the aerodynamic controller is disconnection and Reaction-jet controller is used only. In the first part, the model of the Reaction-jet control system is given; then, the Reaction-jet controller has been designed by using variable structure control. Finally it is proved by simulation that this multiple controller can greatly enhance response speed and has well robustness to the effect of jet interaction.
