Study on Dynamic Decoupling Design by Using INA Method for Cruise Missile

摘要

The non-square model of cruise missile is strongly coupled between roll and yaw channels when the autopilot is design. Multi-variables coupling analysis is completed with a directive gain matrix for the non-square system. Then the non-square system is squared with coupling analysis and inner feedback. An extended dynamic decoupling method by using INA is presented for a dynamic pre-compensator design of a cruise missile non-square system. The mathematical simulation results indicate that the coupling effect is obviously weaken after using the dynamic decoupling compensator and drive a conclusion that the method is valid.
