An Adaptive Control Algorithm for Acquisition of Pneumatic Commutator Data
Abstract
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.
