Item type:Publication, Access status: without files , Optimal load sharing for serial compressors via modifier adaptation(IEEE, 2018-11-27); Mercangöz, MehmetThis paper investigates the optimal load-sharing problem of serial gas compressors in the presence of plant- model mismatch. The problem is formulated as a static real- time optimization task that is solved via modifier adaptation for interconnected systems. The proposed approach guarantees optimal operation of the plant upon convergence. Furthermore, it is shown how the specific problem structure can be exploited during process operation for the efficient estimation of plant gradients with respect to local inputs. A simulated case study demonstrates the effectiveness of the proposed real-time optimization approach.Publicationtype: Conference Paper9 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Distributed modifier adaptation using a coordinator and measured interconnection variablesWe propose a distributed real-time optimization scheme for structurally uncertain systems consisting of multiple interconnected subsystems. In particular, we investigate a novel distributed variant of modifier adaptation that exploits a coordinator and knowledge of interconnection model. This way, each subsystem can compute its optimal inputs using only local information in terms of model, gradients and measurements. A coordinator ensures that the local optimal inputs computed by each subsystem are consistent with the interconnection model. In addition to ensuring confidentiality of local data, the scheme also guarantees plant optimality upon convergence. The analysis is illustrated via a simulation example.Publicationtype: Conference Paper4
