This report describes and documents an adaptive control algorithm currently used in the Propulsion Wind Tunnel Transonic and Supersonic tunnels for the acquisition of steady-state pressure data using pneumatic commutators. The algorithm employs a classification process to determine whether or not data smoothing is required. If filtering is required, then a self-adjusting arithmetic averaging technique is used. Data obtained using the algorithms are acquired subject to both a settling criterion and a time constraint. The report contains a description of the basic instrumentation system and adaptive control algorithm.
