The objective of designing a control structure that takes the degradation of the system into account is to preserve its performance and mitigate further damage. This problem is often encountered in process industries, e.g. in gas processing plants, where the question arises how to distribute the control effort among multiple actuators based on their degradation. The main focus of this work is to investigate how to assign the loads in a two-compressor system taking the degradation, i.e. the loss of available performance, into consideration. Contrarily to other approaches, such as methods based on distance to surge or predictive control, the algorithm proposed in this work does not require a reconfiguration of the control structure, at the same time taking explicitly the degradation into account. The simulation results confirm that this approach mitigates further loss of performance, in particular for compressors, which have significantly different degradation rates. *Financial support is gratefully acknowledged from the Marie Curie Horizon 2020 EID-ITN project "PROcess NeTwork Optimization for efficient and sustainable operation of Europe's process industries taking machinery condition and process performance into account PRONTO", Grant agreement No 675215.

“…(1)-(2c). The data come from the experimental system reported in Cortinovis et al [22], who analysed a control system for a single compressor. It is assumed that the geometrical parameters of the compressor, as well as the volumes of the intermediate discharge tanks and the inertia of the shaft are the same in both compressors.…”

“…In the first approach, proposed in [8], the model is derived from first principles using the assumption that a compressor system can be modelled as an isentropic process in series with an isobaric process including enthalpy increase [7]. The next approach, widely used in the literature, uses third order polynomials to approximate the compressor map [4,7,13]. Finally, the Chebyshev approximation is described which so far has not been used in dynamic modelling of a compressor.…”

“…In [1] and [3] the relationships between compressor control and surge protection were analyzed, comparing PID and MPC controllers. Transient behaviour analysis in case of disturbances from electrical grid was analyzed in [2] where the responses of the compressor during driver trips were analyzed and in [4] where a control algorithm protecting against such trips was proposed. A model-based approach was also used in [5] for analysis of the behaviour of a degrading subsea compressor.…”

The aim of this study is to apply a Chebyshev polynomial approximation of the compressor map for dynamic modelling and control of centrifugal compressors. The results are compared to those from an approximation based on the third order polynomials and a compressor map derived from first principles. In the analysis of centrifugal compressors, a combination of dynamic conservation laws and static compressor map provides an insight into the surge phenomenon, whose avoidance remains one of the objectives of compressor control. The compressor maps based on the physical laws provide accurate results, but require a detailed knowledge about the properties of the system, such as the geometry of the compressor and gas quality. Third order polynomials are usually used as an approximation for the compressor map, providing simplified models at the expense of accuracy. Chebyshev polynomial approximation provides a trade-off between the accuracy of physical modelling with the ease of use provided by third order polynomial approximation.

This paper presents experimental tests of full-scale two-shaft gas turbine in the range of open anti-surge valve (ASV). The tests were carried out in a laboratory gas-turbine test stand belonging to Department of Automation and Power Engineering , Faculty of Ocean Engineering and Ship Technology , Gdańsk University of Technology. The tests covered the start-up and low load operation of the turbine set in the range of open anti-surge valve.
