Accés obertWe describe a multicellular approach to control a target cell population endowed with a bistable toggle-switch. The idea is to engineer a synthetic microbial consortium consisting of three different cell populations. In ... -
Non-uniform sampling in digital repetitive control systems: An LMI stability analysis
(2009-03)
Report de recerca
Accés obertDigital repetitive control is a technique which allows to track periodic references and/or reject periodic disturbances. Repetitive controllers are usually designed assuming a fixed frequency for the signals to be ... -
Novel slow–fast behaviour in an oscillator driven by a frequency-switching force
(2023-04)
Article
Accés obertWhen an oscillator switches abruptly between different frequencies, there is some ambiguity in deciding how the system should be modelled at the switch. Here we describe two seemingly natural models of a switch in a simple ... -
