The paper contributes to the understanding of the behavior of adaptive control systems in anomaly situations. In particular it explores phenomena which are due to interaction between disturbances and unmodeled dynamics. It is shown that the persistency of excitation plays a major role. Ways to ensure that difficulties do not occur are also presented.

Denna utvärderingsrapport behandlar en teknikkurs för kvinnor med olika former av arbetshandikapp. Kursen ingick i BRYT-projektet och utvecklades i samverkan mellan Länsarbetsnämnden i Skåne och Af Rehabilitering. Flertalet av deltagarna uppgav att kursen ökat deras kunskaper och intresse för arbete med teknisk inriktning. Av de sammanlagt tjugo deltagarna hade vid kursens slut en deltagare fått l

We present an experimental study of velocity fluctuations in quasistatic flow of a 2D granular material deformed in a shear apparatus named 1γ2ε [1]. Radjaï and Roux [2] revealed systematic similarities between velocity fluctuations observed in discrete element simulations of quasistatic flow of granular material and turbulent flows in fluids. The character of these velocity fluctuations - named g

This paper focuses on the design and the evaluation of a three-phase permanent magnet synchronous machine (PMSM) that stator core is made of Soft Magnetic Mouldable Composite – SM2C. A radial flux PM machine with modular winding is designed for a high-speed low-voltage automotive application. Manufacturability and a high fill factor of the winding are vital for a low permeability stator core in or
