Modeling of linear fading memory systems [PDF]
, 1996 Motivated by questions of approximate modeling and identification, we consider various classes of linear time-varying bounded-input-bounded output (BIBO) stable fading memory systems and the characterizations are proved.

Limiting equations and some stability properties for asymptotically almost periodic functional differential equations with infinite delay [PDF]
Tohoku Mathematical Journal, 2002 For \(u: \mathbb{R}\to\) Banach space \(X\), the equation considered is \[ u'(t)= Au(t)+ F(t, u_t)\quad\text{for }t\in \mathbb{R}^+:= [0,\infty),\tag{\(*\)} \] where \(u_t:= u(\cdot+ t)|\mathbb{R}^-\), \(\mathbb{R}^-:= (-\infty,0]\), \(A\) is the infinitesimal generator of a compact semigroup \((T(t))_{t\in\mathbb{R}^+}\) of bounded linear operators on

A Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller
International Journal of Adaptive Control and Signal Processing, EarlyView.Block Diagram of the Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller. ABSTRACT This article introduces a discrete‐time robust adaptive one‐sample‐ahead preview super‐twisting sliding mode controller. A stability analysis of the controller by Lyapunov criteria is developed to demonstrate its robustness in handling both ...
