High Gain Observer Design for Eth Helicopter

This paper deals with the design of a high gain observer (HGO) for the ETH helicopter laboratory process. The standard format of high gain observer is used and the parameters of the observer are selected in such away that the observer gain matrix H₀ becomes Hurwitz. The observer not only estimates the angular positions and velocities of the system but also rejects the disturbance and the measurement noise. The simulation results show the effectiveness of the HGO
