In the remainder of t visual .net 3 of 9 his chapter we survey many of the control techniques to be developed over the course of this book. We begin with the uid model in Section 4.

3. After describing general classes of feedback laws, we then begin what will become an on-going discussion on how to translate a policy from the uid model to a more realistic discrete and stochastic network model..

Control Techniques for Complex Networks Draft copy April 22, 2007. 4.3 Control techniques for the uid model The uid model can be Visual Studio .NET Code 3 of 9 viewed as a state space model with state process q, constrained to the polyhedral state space X R , and controlled by the cumulative allocation + process z with rate-constraints speci ed in (6.2).

The control approaches described in d+ this section are de ned through state feedback, (t) = dt z(t; x) = f (q(t)), where the feedback law f is a measurable function from X to the control set U. The feedback law is said to be stabilizing if q(t; x) 0 as t , from each initial condition x. A stabilizing feedback law can only exist if < 1.

It is assumed throughout this section that the state space is of the following form, X = {x R : xi bi , + 1 i } (4.35). where 0 < bi f or each i. When bi = we interpret xi bi as a strict inequality. Recall the de nition of the velocity space V in (4.

26). Policies for the uid model must always respect the following constraints: Given any x X, the allocation rate satis es U, and the corresponding velocity vector v = B + V satis es, vi 0, 0, if xi = 0; if xi = bi , i {1, . .

. , }. (4.

36). Many of the policies VS .NET 3 of 9 barcode considered in this book are based on a cost function that re ects our desire to control the dynamic behavior of the network. It is assumed here that the cost function c : X R+ is a linear function of queue-lengths, of the form c(x) = cT x, with ci > 0 for each i = 1, .

. . , .

A typical choice is the 1 -norm or total inventory c(x) = . x. := i xi . Extensions Code 3/9 for .NET to piecewise linear or smooth convex cost functions are considered in later chapters.

In Section 6.3.2 we discuss control techniques for routing models based on a cost function depending on allocation rates.

We have already considered formulations of optimal control for the uid model. Here are three criteria that are most useful in the applications considered elsewhere in this book. Time optimal control mizes, For each initial condition q(0) = x, nd a control that miniT (x) = min{t : q(t; x) = 0}.

In nite-horizon optimal control that minimizes the total cost, For each initial condition q(0) = x, nd a control. J(x) =.
