Abstract

Guaranteeing stability of control applications in
embedded systems, or cyber-physical systems, is perhaps the
alpha and omega of implementing such applications. However,
as opposed to the classical real-time systems where often the
acceptance criterion is meeting the deadline, control applications do not primarily enforce hard deadlines. In the case
of control applications, stability is considered to be the main
design criterion and can be expressed in terms of the amount
of delay and jitter a control application can tolerate before
instability. Therefore, new design and analysis techniques are
required for embedded control systems.
In this paper, the analysis and design of such systems
considering server-based resource reservation mechanism are
addressed. The benefits of employing servers are manifold: (1)
providing a compositional framework, (2) protection against
other tasks misbehaviors, and (3) systematic bandwidth assignment. We propose a methodology for designing bandwidth-efficient servers to stabilize control tasks.
