Summary, in English
with one or more servers that process incoming requests. Since service control nodes are sensitive to
overload, admission control mechanisms are often implemented. In this paper, we model and analyse
admission control mechanisms for server systems with control theoretic methods. We develop a nonlinear
stochastic control theoretic model of a GI/G/1-system. Further, we show that this model can be
used to design admission control mechanisms that behave well in the “real” system, that is the queuing
system. We develop two types of controllers for the system, one PI-controller and one RST-controller,
both commonly used in automatic control. Also, we discuss some of the limitations of previous work in
this area, in which only deterministic and linear models have been used.
