Large control signal derivatives or inter-sample differences may harm actuators. An optimization constraint limiting such variations, related to measurement noise, is derived. Using the constraint, optimal PI, PID and measurement filters with different orders are designed for several processes and compared to the optimal linear controller of high order found via Youla parametrization.

Ett skattningsinstrument som mäter negativa och positiva känslor med en kombination av visuella analogskalor, kallat hälsobarometer, har testats bland kvinnor med långvarig värk och smärta. Hälsobarometern är enkel att fylla i, och den ger en omedelbar visuell bild av hur patienten mår. Den ger därmed en vink om var man ska lägga tonvikten på det utforskande samtalet. Hälsobarometern visar sig s
Recursive state estimation is considered for discrete time linear systems with mixed process and measurement disturbances that have stochastic and (convex) set-bounded terms. The state estimate is formed as a linear combination of initial guess and measurements, giving an estimation error of the same mixed type (and causing minimal interference between the two kinds of error). An ellipsoidal over-

Kort sammanfattning: Energimyndigheten, Vetenskapsrådet och Vinnova har stött ESS Skandinavien Sekretariatet med 3 Mkr för att undersöka hållbara energi¬lösningar. Resultatet har blivit att ännu större resurser har bidragits från samarbetande industri. Arbetet är fortfarande i ett tidigt skede av utvecklingen, men preliminära beräkningar visar att besparingarna för ESS kan uppgå till fyra gånger dAbstract: Energimyndigheten, Vetenskapsrådet and Vinnova have supported the ESS Scandinavia Secretariat with 3 MSEK to explore sustainable energy solutions. The result has been that even greater resources have been contributed by cooperating industry. The work is still in early stages of progress, but preliminary calculations indicate that the savings for ESS might amount to four times the initial

In the RUNES project a disaster relief tunnel scenario is being developed in which mobile robots are used to restore the radio network connectivity in a stationary sensor network. A component-based software development approach has been adopted. Two components are described in this paper. A localization component that uses ultrasound and dead reckoning to decide the robot positions and a collision
