Design of Robust Controllers for a Rotary Wing Helicopter
(2013-06)
Due to inherent instability, parametric variations, changing properties during flight, and uncertainties in predicting aerodynamic coefficients, helicopter flight control requires strategies with enough robustness to cope ...
Nonlinear Adaptive Control of Quadrotor
(2014-02)
In this research, nonlinear and adaptive controls of quadrotors are designed. The system is considered as an under-actuated system, which has six degrees of freedom (DOF) and four actuators. In addition, a nonlinear model ...
