Contents I. Introduction
Sampled-Data control constitutes an essential feature in mechatronics. Indeed, mechatronic systems are composed of mechanical plants, whose dynamics (often nonlinear) belongs to the continuous-time, driven by digital controllers, which evolve in discrete sampling times. Instead of designing discrete-time controllers from discretized models (see, e.g., [1], [2]), which necessitate sufficiently small constant sampling periods, the input time-varying delay approach, initially proposed for the sampled-data of continuous-time linear systems [3]–[5], constitutes an appealing alternative. Indeed, it allows enlarging non-uniform sampling intervals, which is useful, especially for mechatronics, embedded or network control systems, yielding to reduced online computational cost (e.g., for better reliability or economy reasons) or to cope with feedback-induced delays, due to analog to digital conversions, packet loss, among others.
