Model reference variable structure autopilot design for homing missile

The control system for a homing missile was designed, so that the autopilot can transfer guidance command correctly and can be robust to disturbance, such as the measurement noise and parameter variation caused by aerodynamic floating. The model reference adaptive control was combined with the variable structure control to design a model reference variable structure (MRVS) control system whose control structure is simple and can be realized easily. The simulation results indicate that MRVS can complete the task of transferring guidance command and suppress the disturbance.
