In this paper a collection of control algorithms which are able to give rise to 2-sliding modes
have been presented, and for each of them the sufficient convergence conditions are given. …

… Introduction From a reductionistic perspective, many brain circuits have evolved as
hierarchical networks of excitatory glutamatergic neurons and g-aminobutyric acid-containing (…

Relying on the possibility of generating a second-order sliding motion by using, as control,
the first derivative of the control signal instead of the actual control, a new solution to the …

… The ‘global’ 2-SMC has been recently proposed by the authors (Bartolini et al. 2001b), and
it is based on constraining the trajectory of the sliding variable within a pre-specified region of …

A solution to the problem of eliminating the chattering effect, which is always associated with
practical implementations of variable structure control, is presented with reference to a class …

Olive (Olea europaea L.) is an evergreen xerophytic tree characterizing vegetative landscape
and historical-cultural identity of the Mediterranean Basin. More than 2600 cultivars …

The solution of a tracking problem for a secondorder nonlinear system with uncertain dynamics
and incomplete state measurement is obtained by means of a procedure directly inspired …

Discrete-time sliding mode control is considered. The case of known parameters is first
analyzed, leading to a new definition of the so-called ‘equivalent control’ as the piecewise-…

A (3) no more than five methylenes are connected to branched carbon atoms; and (4) the two
secondary methyl groups are attached to methines which are ß to branched carbon atoms. …

INTRODUCTION The cerebral cortex is a cellularly heterogeneous structure whose neuronal
circuits underlie high-order cognitive and sensorimotor information processing. Neocortical …
