...Jia‐hui Luan; Ting‐di Zhao Purpose This paper aims to present a novel fault estimator design scheme, in order to improve the practicability of the fault estimation. Design/methodology/approach The paper first transforms the system state into three parts. Then a reduced‐observer is designed...

...K. Bousson Purpose This paper is concerned with an online parameter estimation algorithm for nonlinear uncertain time‐varying systems for which no stochastic information is available. Design/methodology/approach The estimation procedure, called nonlinear learning rate adaptation (NLRA...

... of lunar rovers are introduced. Then, matched‐features set is build by multi steps of image processing such as feature detection, feature tracking and feature matching. Based on the analysis of the image processing error, a two‐stage estimation algorithm is used to estimate the motion, robust linear motion...
