  1. 1. Model-Based Design, Development and Control of an Underwater Vehicle

    University essay from Linköpings universitet/Reglerteknik

    Author : Adam Aili; Erik Ekelund; [2016]
    Keywords : Model; Design; Development; Control; Underwater; Underwater vehicle; BlueROV; ROV; Fossen; Modelling; Parameter Estimation; Prediction-error method; Extended Kalman filter; EKF; Feedback linearisation; Attitude controller; Angular velocity controller;

    Abstract : With the rising popularity of ROVs and other UV solutions, more robust and high performance controllers have become a necessity. A model of the ROV or UV can be a valuable tool during control synthesis. The main objective of this thesis was to use a model in design and development of controllers for an ROV. READ MORE

  3. 2. Model Based Automatic Tuning and Control of a Three Axis Camera Gimbal

    University essay from Linköpings universitet/Reglerteknik; Linköpings universitet/Tekniska fakulteten

    Author : Henric Edlund; [2015]
    Keywords : system identification; feedback linearisation; camera gimbal;

    Abstract : A gimbal is a pivoted device that decouples movements of a platform from its payload. The payload is a camera which must be stabilized to capture video without motion disturbances. A challenge with this type of gimbal is that a wide span of cameras with different sizes and weights can be used. READ MORE

  4. 3. Attenuation of Harmonic Distortion in Loudspeakers Using Non-linear Control

    University essay from Reglerteknik; Tekniska högskolan

    Author : Marcus Arvidsson; Daniel Karlsson; [2012]
    Keywords : EKF; exact linearisation; feed-forward; loudspeaker modelling; non-linear control; UKF;

    Abstract : The first loudspeaker was invented almost 150 years ago and even though much has changed regarding the manufacturing, the main idea is still the same. To produce clean sound, modern loudspeaker consist of expensive materials that often need advanced manufacturing equipment. READ MORE

  5. 4. 2.4 GHz Power Amplifier with Cartesian Feedback for WLAN

    University essay from Institutionen för systemteknik

    Author : Maria Hofvendahl; [2002]
    Keywords : Electronics; Linearisation; Cartesian feedback; IMD; 1dBcompression point; PA; mixer; subtracter; adder; RF; Elektronik;

    Abstract : This final year project describes the linearisation method Cartesian feedback and the design of such a feedback with a 2.4GHz power amplifier. To investigate the functionality of the Cartesian feedback ideal blocks with no current consumption were made and then gradually analog circuits were introduced into the feedback. READ MORE

  6. 5. Linear and Neuro Control Strategies; Some Experimental Results

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Henrik Olsson; [2000]
    Keywords : Technology and Engineering;

    Abstract : The variety of different controllers is today very big. Much research is done in the field of neural network control and more well established technologies are sometimes looked at as old fashioned. The work is much based on the identification of a process model. READ MORE
