  1. 31. Power Electronic Stages for a TFPMSM in Wave Power Applications

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Gustaf Falk Olson; [2016]
    Keywords : transverse flux permanent magnet synchronous machine TFPMSM ; active rectifier; direct drive wave energy converter; feedback linearization; cascaded PID controller.;

    Abstract : Direct drive wave energy conversion systems have been identified as a potentially major contributor to the world’s energy demands, forecasting shares of up to 25 % of the energy mix. Anders Hagnestål conducts research at the Royal Institute of Technology where a novel linear transverse flux permanent magnet generator is developed. READ MORE

  3. 32. Behavioral Modeling of Power Amplifier with Memory Effect and Linearization Using Digital Pre Distortion

    University essay from Högskolan i Gävle/Elektronik

    Author : Om Prakash Nandi; [2016]
    Keywords : Behavioral Modeling; Power Amplifier; DPD;

    Abstract : This thesis work studied the behavioral modeling, estimation of parameters, model performance and linearization of power amplifier (PA) using Digital Pre Distortion (DPD) technique. PAs are one of the fundamental block in communication systems and also one of the main sources of nonlinearities in the system, as these devices are frequently subjected to signals characterized by considerable bandwidths and non-constant envelopes due to use of modern modulation technique.

  4. 33. Different Digital Predistortion Techniques for Power Amplifier Linearization

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Ibrahim Can Sezgin; [2016]
    Keywords : DPD; Digital Predistortion; Forward Behavioral Modeling; Power Amplifier; Non-Linearity; Memory Effect; Volterra Series; Memory Polynomial; Generalized Memory Polynomial; Simplified Volterra Series; Augmented Complexity Reduced Generalized Memory Polynomial; Augmented Complexity Reduced Simplified Volterra; Technology and Engineering;

    Abstract : Linearity and high efficiency are crucial requirements for any power amplifier. However, power amplifiers have high efficiency levels when they are in non-linear regions. To overcome this issue there have been many suggestions in literature, one of the most successful methods is digital predistortion method. READ MORE

  5. 34. Non-Linear Automatic Control of Autonomous Lawn Mower

    University essay from Linköpings universitet/Reglerteknik

    Author : Hannah Dysenius; [2016]
    Keywords : autonomous lawn mower; non-linear automatic control;

    Abstract : This master thesis contains modeling and nonlinear automatic control of an autonomous lawn mower. The vehicle shall be able to follow a magnetic field loop buried in the lawn on an arbitrary distance, including straddling. A unicycle model of the lawn mower has been derived based on previous work. READ MORE

  6. 35. Automated Controller Design for a Missile Using Convex Optimization

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Christoph Auenmüller; [2016]
    Keywords : control; missile; windup; convex; optimization; lmi; automation;

    Abstract : The focus of the present master thesis is the automation of an existing controllerdesign for a missile using two aerodynamic actuating systems. The motivation isto evaluate more missile concepts in a shorter period of time.The option used is trimming and linearization of a highly nonlinear missile at specic conditions. READ MORE
