  We present an application of equation-free computation to the coarse-grained
feedback linearization problem of nonlinear systems described by
microscopic/stochastic simulators. Feedback linearization with pole placement
requires the solution of a functional equation involving the macroscopic
(coarse-grained) system model. In the absence of such a closed-form model,
short, appropriately initialized bursts of microscopic simulation are designed
and performed, and their results used to estimate on demand the quantities
required for the numerical solution of the (explicitly unavailable) functional
equation. Our illustrative example is a kinetic Monte Carlo realization of a
simplified heterogeneous catalytic reaction scheme
