Constructing a workload model for a node of a Grid system is considered in terms of control theory. A node is represented as a linear dynamic object acted upon by perturbations with unknown statistical properties. Fuzzy set estimates are used to evaluate the state of the object. They ensure the robustness of the algorithm proposed and its usability under the lack of a priori information on the unknown vector and the inaccuracy of current measurements.
