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

    Author : Claes Olsson; Alexander Medvedev; Stephen Elliott; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Estimation and Control of Resonant Systems with Stochastic Disturbances

    Author : Peter Nauclér; Torsten Söderström; Anders Robertsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration control; stochastic control; stochastic systems; feedforward control; Wiener filtering; Kalman filtering; wave separation; unbalance estimation; nonlinear regression; Automatic control; Reglerteknik;

    Abstract : The presence of vibration is an important problem in many engineering applications. Various passive techniques have traditionally been used in order to reduce waves and vibrations, and their harmful effects. Passive techniques are, however, difficult to apply in the low frequency region. READ MORE

  5. 3. On Modeling and Control of Flexible Manipulators

    Author : Stig Moberg; Svante Gunnarsson; Anders Robertsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; multivariable systems; differential-algebraic equations; robots; manipulators; flexible structures; robustness; position control; nonlinear systems; closed-loop identification; frequency-response methods; industrial robots; robotics; control; feedforward; flexible arms; Automatic control; Reglerteknik;

    Abstract : Industrial robot manipulators are general-purpose machines used for industrial automation in order to increase productivity, flexibility, and quality. Other reasons for using industrial robots are cost saving, and elimination of heavy and health-hazardous work. READ MORE

  6. 4. Modelling and Control Methods with Applications to Mechanical Waves

    Author : Hans Norlander; Bengt Carlsson; Torsten Söderström; Jonas Sjöberg; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automatic control; pole placement; linearization; vibration control; distributed parameter systems; wave propagation; Automatic Control; Reglerteknik;

    Abstract : Models, modelling and control design play important parts in automatic control. The contributions in this thesis concern topics in all three of these concepts.The poles are of fundamental importance when analyzing the behaviour of a system, and pole placement is an intuitive and natural approach for control design.
