Decoupling Control Methods for Spinning Missiles

摘要

Decoupling control is one key component during the design of autopilot for spinning missiles. However, in addition to the strong dynamic coupling effect, its parameters vary very fast over a large range, which induces great challenge to the design of autopilot. To address this issue, the classic complex summation decoupling control method and the newly developed robust gain-scheduling control method are both studied in detail, which are then applied to the design of autopilot of the spinning missile. The results from comparative studies show that the complex summation decoupling control method yields poor tracking performance and robustness; while the robust gain-scheduling control method performs much better during the whole trajectory. It is indicates that the robust gain-scheduling control method is very applicable to the spinning missile with strong dynamic coupling, and large fast time-varying parameters.
