Abstract :
Observers for a compression system using turbo compressors are derived for a model that captures the phenomena of surge. Both a full order observer for pressure, mass flow and impeller speed and a reduced order observer for mass flow are presented. The observers assume measurements of pressures and impeller speed. Results are validated by simulations.
