In this work a remote lab developed to explore the properties of event-based controllers is presented. The architecture is based on the decomposition of the system in three tiers. The server layer is directly connected to the plant, the client side implements the controller and the graphical interface, and the middle-tier acts as interface between client and server. The implementation of the remote lab allows the control of a Coupled Tank plant through a generic network. The platform is used to evaluate the effectiveness of an algorithm that allows the user to find numerically the limit cycles in control schemes where the feedback is done through a level crossing sampling, and which can be applied to LTI systems with delay.

Abstract
In this work a remote lab developed to explore the properties of event-based controllers is presented. The architecture is based on the decomposition of the system in three tiers. The server layer is directly connected to the plant, the client side implements the controller and the graphical interface, and the middle-tier acts as interface between client and server. The implementation of the remote lab allows the control of a Coupled Tank plant through a generic network. The platform is used to evaluate the effectiveness of an algorithm that allows the user to find numerically the limit cycles in control schemes where the feedback is done through a level crossing sampling, and which can be applied to LTI systems with delay.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
