Abstract:

The finite-time stability of robotic arm systems against Denial of Service attacks, when the link between the plant and the controller is often interrupted was studied in this paper. In order to do this, a method is suggested that relies on an event-triggered mechanism which is based on the rate of change of the Lyapunov function, that keeps the system finite-time stable while simultaneously reducing the quantity of data interchange in the network. The suggested event-triggered finite-time controller’s vulnerability to Denial of Service attacks is then assessed, and sufficient limitations on the length of a Denial of Service are identified to ensure the system’s stability within a specified time frame. Lastly, a simulation study is used to show how effective the suggested strategy is.
