具側噴流之傾斜轉彎飛彈自動駕駛儀設計

本論文中，將討論如何將傾斜轉彎控制的飛彈與前置側噴流系統結合。此飛彈彈體具非對稱結構，且採用傾斜轉彎飛行的方法，利用將彈體滾轉到最大氣動力的方向使其與運動方向一致的方式，試圖提高飛彈的機動性能。但此方法會引起高度的非線性效應及耦合，造成自動駕駛儀設計的困難。本論文討論傳統側滑轉彎的設計方法，忽略各軸間的耦合作用，進行線性化後對各軸獨立設計。接著將自動駕駛儀代入非線性模式，觀察其模擬結果。再在飛彈上加入前置側噴流系統。側噴流可即時對飛彈產生一股側推力及較高的攻擊角，使飛彈的機動性瞬間提高。最後進行具側噴流系統的模擬，並討論有無側噴流系統的優缺點及須要改進的地方。

In this thesis, we discuss how to combine a lateral jet system into bank-to-turn (BTT) missiles. The missile exploits the bank-to-turn control method in conjunction with asymmetrical airframes. When the missile is commended to roll, the direction of maximum aerodynamic normal force is oriented to the desired movement direction, and the maneuverability of the missile is increased. However nonlinearities and coupling effects caused by the high rolling rate in the BTT motion make the controller design very difficult. Here we utilize the traditional skid-to-turn (STT) design method. Neglecting the coupling among roll, pitch, and yaw axes, we first use the linearization technique and design linear controllers for every axis independently. Then we carry out simulations with the nonlinear model, and add a lateral jet to the frond end of the missile. The front lateral jet system can produce large lateral force and a higher attack angle instantaneously so that the missile has higher maneuverability. The simulation results of the present study do show the benefit of this device Keywords: BTT, Autopilot, Lateral jet
