In this paper a disturbance observer based PD controller is proposed for a Reusable Launch Vehicle (RLV) in ascent phase. Disturbance observer based control is an effective way of achieving disturbance rejection and robustness to plant uncertainties. Here it is used for observing and stabilising the flexible mode in RLV. The disturbance observer makes the actual flexible plant dynamics similar to...
Localization is a key aspect of planetary exploration rovers. Visual odometry algorithm can give improved motion estimates compared to conventional systems (Wheel encoders/Inertial measurement units) when traveling in Steep/Sandy terrains. This paper gives the details of a Visual odometry algorithm developed for future planetary exploration rovers. A new algorithm to improve the feature matching and...
