Abstract :
A novel approach combining the sliding mode control and extended state observer is proposed for attitude control of a quaternion missile model which is nonlinear in aerodynamics. Combining the back-stepping technique, the corresponding sliding mode controller is designed to guarantee the state variables of the closed loop system to converge to the reference state with the help of the extended state observer by estimating the uncertainties. Also, simulation results are presented to illustrate the effectiveness of the control strategy.
