Dynamic Inversion과 PI 제어를 이용한 견실한 유도탄 오토파일롯 설계

Robust Missile Autopilot Design using Dynamic Inversion and PI Control

This paper presents a robust nonlinear autopilot design method based on dynamic inversion and PI(Proportional-Integral) control law. The new controller structure which is different from previous work is composed of classical linear PI control law and nonlinear fast dynamic inversion. A pitch axis model of highly maneuverable missiles and a linearized model for designing Pl controller are presented. The performance of proposed method is illustrated via nonlinear simulations including aerodynamic uncertainties and actuator dynamics.
