Modeling and robust attitude control of a quadrotor system

This paper describes the no-lineal model, and attitude Robust control of a Quadrotor MIMO System (UAV). The dynamic model of the UAV is transformed into a LTI system and approximated by a SISO system due to the low coupling among the canals of the system. The unknown model parameters have been taken of the system implemented in the Center for Research and Advanced Studies of the National Polytechnic Institute (CINVESTAV). Finally, robust controller has been designed using H∞ theory. The effectiveness and performance of the proposed control approach have been proved in simulation using MATLAB.
