In this paper. we consider the state estimation problem for flexible joint manipulators that involve nonlinear characteristics in their stiffness. The two key ideas of our design are that (a) an accelerometer is used in order that the estimation error dynamics do not depend on nonlinearities at the link part of the manipulators and (b) the model of the nonlinear stiffness is indeed a ... https://www.diegojavierfares.com/quick-offer-Explore-Caravan-Scissor-Jack-ADR-Australian-Standard-1600Kg-CSJ1600-mega-choice/
