On Limit Cycles in Event-Based Control Systems

In English Event-based control is a promising alternative to
time-triggered control, especially for systems with limited
computation and communication capacities. In the paper, the
architecture of a general structure for event-based control is
presented. The resulting system has many interesting properties. For
instance, a constant load disturbance will typically make the
process output oscillate according to a stable limit cycle.
Necessary conditions for the limit cycle are given and its local
stability is analyzed. Finally, a simple way to achieve integral
action based on times between events is proposed.
