Abstract

At high angles of attack, aircraft dynamics can display an oscillatory lateral behavior that manifests itself as a limit cycle known as wing rock. In this paper, a classical and neural network based adaptive control design methods of adaptively stabilizing the oscillatory motion by adapting uncertainties are described in detail. All methods are simulated and compared using a model for an 80o swept delta wing.

높은 받음각에서 항공기는 Wing Rock 이라고 알려진 Limit cycle 형태의 횡방향 진동 운동을 보일 수 있다. 이 논문에서는 이러한 불안정 진동운동과 관련한 불확실성에 적응하여 안정화시키는 고전 및 신경회로망기반 적응제어기법들의 상세 설계내용을 제시하였다. 모든 기법들은 80도 후퇴각을 가진 삼각날개를 갖는 모델에 적용하여 시뮬레이션하였고 그 결과를 비교분석하였다.
