Triggered Repetitive Control: Application to Mechanically Ventilated Patients

Asymptotic rejection of a periodic disturbance can be achieved using repetitive control (RC). The aim of this article is to develop a triggered RC (TRC) framework that can handle repeating tasks that are initiated by an external disturbance induced trigger on varying intervals, which clearly violate...

Description
Summary:Asymptotic rejection of a periodic disturbance can be achieved using repetitive control (RC). The aim of this article is to develop a triggered RC (TRC) framework that can handle repeating tasks that are initiated by an external disturbance induced trigger on varying intervals, which clearly violates the periodicity assumption in RC. A design method for this TRC framework is presented with a stability guarantee. Finally, through an experimental use-case, it is shown that pressure tracking performance for mechanically ventilated patients is improved significantly.
