A method for synthesizing proportional-integral-derivative (PID) controllers for process models with probabilistic parametric uncertainty is presented. The proposed method constitutes a stochastic extension to the well-studied maximization of integral gain optimization (MIGO) approach, i.e., maximization of integral gain under constraints on the H-infinity norm of relevant closed-loop transfer fun
Parallel architectures are essential in order to take advantage of the parallelism inherent in streaming applications. One particular branch of these employ hardware SIMD pipelines. In this paper, we analyse several scheduling techniques, namely ad hoc overlapped execution, modulo scheduling and modulo scheduling with unrolling, all of which aim to efficiently utilize the special architecture desi
Popular Abstract in Swedish Det elektriska kraftsystemets uppgift är att ge konsumenter en säker och stabil energitillgång till lägsta möjliga kostnad. Sett ur ett ingenjörsperspektiv tillkommer några extra krav såsom att variationerna i spänning och frekvens skall vara acceptabla, samt att enstaka komponenters kapacitetsgränser ej överskrids. Om dessa krav ej uppfylls kan detta leda till leverans
This paper develops a novel framework for power system stability analysis, that allows for the decentralised design of inverter based controllers. The method requires that each individual inverter satisfies a standard H∞ design requirement. Critically each requirement depends only on the dynamics of the components and inverters at each individual bus, and the aggregate susceptance of the transmiss
In an effort to curb climate change, the electric power system in many countries is transitioning from fossil fuels to more renewable power sources such as wind. At the same time, other countries are decommissioning their old nuclear power, and replacing it with wind power. When replacing synchronous machines with wind power the inertia in the system is decreased. If nothing is done about this the

[Context and motivation] In market-driven software development it is crucial, but challenging, to find the right balance among competing quality requirements (QR). [Problem] In order to identify the unique challenges associated with the selection, trade-off, and management of quality requirements an interview study is performed. [Results] This paper describes how QR are handled in practice. Data i
Hundreds of PID design methods are available in literature. Many of them are very similar and sometimes it is not straightforward to understand their purposes. This paper presents an interactive software tool to help in the study and understanding of several wellknown PID tuning rules. Frequency- and time-domain responses are analyzed in order to show the robustness and performance properties of e

Kompetenscentret AdTherM inriktar sig på analyser av termiska processer i industriella tillämpningar, inklusive termo- och elektrokemisk energiomvandling. De flesta utmaningar för industrin inom detta område är generiska och baseras på samma fysiska mekanismer. För att utveckla detta forskningsfält måste både experiment och modeller förbättras och samordnas.
