Robust preview tracking control for a class of uncertain discrete-time systems

open access: yesCogent Engineering, 2016
The robust preview control problem of uncertain discrete-time systems satisfying matching conditions is considered. First, for the nominal system, we use the difference between a system state and its steady-state value, instead of the usual difference ...

On the intensity decay of tropical cyclones before landfall

open access: yesScientific Reports, 2022
It remains unclear how tropical cyclones (TCs) decay from their ocean lifetime maximum intensity (LMI) to landfall intensity (LI), yet this stage is of fundamental importance governing the socio-economic impact of TCs.
