A High-Gain Observer for a Wet Gas Centrifugal Compressor

Performance Evaluation of a Centrifugal Compressor Operating under Wet Gas Conditions

This paper presents the results of performance testing of a single-stage centrifugal compressor operating under wet gas conditions. The test was performed at an oil and gas operator’s test facility and was executed at full-load and full-pressure conditions using a mixture of hydrocarbon gas and hydrocarbon condensate. The effect of liquid was investigated by changing the gas-volume fraction bet...

conceptual design of a centrifugal compressor impeller for a 65 kw micro gas turbine

the aim of this study is designing the impeller of a centrifugal compressor in order to supply pressure ratio for a 65 kw micro gas turbine. first, the primary thermodynamic analysis has been conducted for the considered cycle using a home made code. herein, the compressor pressure ratio was considered to be 4. the obtained thermal efficiency was 25.64%. then, the design of micro compressor in ...

Effects of Impeller Gap on Rotor Vibration in a High Speed Centrifugal Compressor: A Numerical and Experimental Analysis (TECHNICAL NOTE)

Centrifugal compressors produce high pressure ratio and rotate at speeds. So, a tiny unbalance can produce severe vibration. In this paper, effects of impeller gap on rotor vibration in a high speed centrifugal compressor is investigated. For this purpose, a numerical and experimental analysis are carried out. The moving reference frame method in FLUENT software is used for modeling of geometri...

A High Gain Observer based LMI Approach

This paper deals with the observability analysis and the observer synthesis of a class of nonlinear systems. The observer that we consider has a constant gain and concerns a class of uniformly observable systems. A sufficient condition permitting to design such a constant gain observer is given. The calculation of this gain is based on LMI technics.Copyright c © 2008 IFAC
