  1. 1. Active Engine Vibration Isolation using Feedback Control

    Författare :Claes Olsson; Ahmed El-Bahrawy; Lennart Ljung; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Broad band active vibration isolation of automobile engine using linear and nonlinear feedback control is considered. The objective is to reduce the forces transmitted to the chassis and body, and, thus, reducing vibrations and structure borne noise inside the vehicle compartment when the engine is subjected to different excitations.

  3. 2. Active Vibration Control of Multibody Systems : Application to Automotive Design

    Författare :Claes Olsson; Alexander Medvedev; Stephen Elliott; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Vibration Control; Vibration Isolation; Feedback Control; Adaptive Filtering; Saturation; Limit Cycles; Multi Body Systems; Modelling; Simulation; Non-linearity; Gain Scheduling; Structure Flexibility; Automatic control; Reglerteknik;

    Sammanfattning : Active vibration control to reduce vibrations and structure borne noise is considered using a powerful multi-disciplinary virtual design environment which enables control system design to be considered as an integral part of the overall vehicle design. The main application studied is active automotive engine vibration isolation where, first, the potential of large frequency band multi-input multi-output H2 feedback control is considered. LÄS MER

  7. 5. Celiac disease in Swedish children and adolescents : variations in incidence and essentials of gluten-free eating with a youth perspective

    Författare :Cecilia Olsson; Ylva Mattsson Sydner; Claes Hallert; Umeå universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Adolescent; Celiac disease; Focus groups; Gluten-free diet; Incidence; Infant feeding; Patient compliance; Primary prevention; Social Constructionism; Stigma; Domestic science and nutrition; Hushålls- och kostvetenskap; Kostvetenskap; Food and Nutrition;

    Sammanfattning : Background Sweden has experienced a unique epidemic of celiac disease (CD) in children younger than 2 years of age. The epidemic was partly explained by changes over time in infant feeding and indicated a multifactorial aetiology. LÄS MER
