Application results for new adaptive control system for working gas pressure in supersonic periodical wind tunnel pretest chamber

摘要

The airflow control system for supersonic periodical wind tunnel (WT) supposed. New internal model regulator (IMC [5]) is used to improve pretest chamber pressure P_0 prohibitive over-regulation detected for "large" Mach numbers (M > 2.3). Verification test in situ have been performed for M = 3.0, 3.5. Results for the new regulator implementation shown.
