Abstract

Quadrotor is simple to model because of the symmetric structure but it has the disadvantage of being relatively sensitive to the external disturbance and system uncertainty. The PID technique applied for the attitude control of quadrotor has been applied comprehensively, but it has a disadvantage that is hard to precise control in the nonlinear system. In this work, a quadrotor attitude control law using the super twisting algorithm is studied, which has robust characteristics against disturbance and system uncertainty. To evaluate the attitude performance by the proposed technique, simulation studies and actual flight tests are carried out, and compared with the conventional PID controller.

쿼드로터는 대칭적인 구조로 모델링이 간단하지만 외란과 시스템의 불확실성에 민감하다는 단점이 있다. 쿼드로터의 제어를 위해 비교적 간단하게 적용이 가능한 PID 제어가 많이 연구되고 있지만, 비선형 시스템에서는 정밀한 제어가 힘들다는 단점이 있다. 본 논문에서는 이를 해결하기 위하여 외란과 시스템의 불확실성에 강인한 특징을 가지는 슈퍼 트위스팅 알고리즘(Super twisting algorithm)을 이용한 쿼드로터 제어를 제안한다. 이 제어기법을 이용하여 쿼드로터의 자세제어기를 구성하였다. 구성한 제어기의 성능을 검증하기 위해 시뮬레이션 및 실제 비행시험을 진행하였다. 제어기의 보다 객관적인 성능 검증을 위해 PID 제어와 성능 비교를 진행하였다.
