abstract = {Classically, a control loop is designed to be executed strictly periodically.<br />This is, however, difficult to achieve in many scenarios, for example, when<br />overload or packet loss cannot be entirely avoided. Here, weakly-hard real-time<br />control systems are a common approach which relaxes timing constraints and<br />leverages the inherent robustness of controllers. Yet, their analysis is often<br />hampered by the complexity arising from the system dimension and the vast<br />number of possible timing sequences. In this paper, we present the novel<br />concept of convergence rate abstractions that provide a sound yet simple<br />one-dimensional system description. This approach simplifies the stability<br />analysis of weakly-hard real-time control systems. At the same time, our<br />abstractions facilitate efficient computation of bounds on the worst-case<br />system state at run-time and thus the implementation of adaptation mechanisms.<br},
