    The problem of modifying the conditions at wind tunnel walls on a systematic basis to minimize the interference about a model is dealt with, and a control law is developed for achieving this end. The approach is general and does not depend on the mechanical means used to measure the flow variables (sensors) or to control the flow variables (actuators). Also, unlike previous control schemes, the present one does not require an iterative approach per se and is valid for both three-dimensional and lifting flows.
