A nonlinear disturbance observer for robotic manipulators [PDF]
IEEE transactions on industrial electronics (1982. Print), 2000 A new nonlinear disturbance observer (NDO) for robotic manipulators is derived in this paper. The global exponential stability of the proposed disturbance observer (DO) is guaranteed by selecting design parameters, which depend on the maximum velocity ...

A Precise Neural-Disturbance Learning Controller of Constrained Robotic Manipulators
IEEE Access, 2021 An adaptive robust controller is introduced for high-precision tracking control problems of robotic manipulators with output constraints. A nonlinear function is employed to transform the constrained control objective to new free variables that are then ...

A method to formulate a dimensionally homogeneous Jacobian of parallel manipulators [PDF]
, 2011 This paper presents a general and systematic approach to formulate the dimensionally homogeneous Jacobian, which is an important issue for the dexterity evaluation and dimensional synthesis of f-degrees-of-freedom (DOF) (f ≤ 6) parallel manipulators ...

Journal of Economic Theory, 2004 The authors consider some kind of manipulative strategic trading performed by informed insiders. The possibility of manipulative trading is investigated in a Glosten-Milgrom type of the dynamic bid-ask model. The market for one risky and one riskless asset and with one trader is considered.

Generalized Jacobian analysis of lower mobility manipulators [PDF]
, 2011 Mainly drawing on screw theory and linear algebra, this paper presents a general approach for Jacobian analysis of lower mobility manipulators. Given the definitions of twist/wrench spaces and their subspaces of the end-effector, the underlying ...
