  1. 1. Development of a Compact Drive System for Total Artificial Heart

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Hossin Bakhtiari; [2023]
    Keywords : Total Artificial Heart; Drive System; Miniaturization; Electric Motor; Motor Performance Evaluation; Motor Selection; Totalt artificiellt hjärta; drivsystem; miniatyrisering; elektrisk motor; motorprestanda utvärdering; motor-urval;

    Abstract : Over eight decades of research into total artificial hearts (TAHs) has significantly contributed  to saving end-stage heart failure patients. However, at the current stage of development TAHs have several limitations, one of them being their bulkiness. READ MORE

  3. 2. Reaction Wheel Control System for a Self-balancing Bike : Reaction wheel based control mechanism for a small scale prototype bike

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Reman Soryani; [2023]
    Keywords : Mechatronics; Control Theory; Reaction Wheel; PID Controller; Robotics; Mekatronik; Reglerteknik; Mekanik; PID reglering; Robotik;

    Abstract : In this thesis, the design of a self balancing prototype bike with a reaction wheel as balancing mechanism will be investigated. Bikes are inherently unstable systems, that dynamically resemble an inverted pendulum at a stand still. READ MORE

  4. 3. Comparative Study of Genetic Algorithm Optimized FO-PID and LQR Control Strategies Applied to a Piston Pump in a Volume Calibration System

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Yaman Deif; [2023]
    Keywords : FOPID; LQR; GA; Servo Piston Pump; BLDC; Control Comparison; System Modeling; Volume Measuring.; FOPID; LQR; GA; Servo Piston Pump; BLDC; Styrjämförelse; Systemmodellering; Volymmätning.;

    Abstract : One of the key responsibilities of Getinge's ventilators is to deliver accurate gas volumes to patients. To ensure this precision, specially designed rigid steel tanks are utilized to evaluate the performance and precision of the ventilators in providing exact air volume. READ MORE

  5. 4. Automatic Torque Control for Bicycle Driven Brushless DC (BLDC) Generator

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Luke Müller; Kasper Sjöström; [2021]
    Keywords : BLDC; brushless dc generator; brushless dc motor; JFET; Torque; Generator Torque; Automatic Torque Control; Field Effect Transistor; PWM;

    Abstract : This work was carried out on behalf of Science Safari. Science Safari wants to create a product that facilitates the understanding of how much physical work is required to create electrical energy. This is done by cranking the pedals of a bicycle. READ MORE

  6. 5. Design, simulation and HIL testing of an electric propulsion system of an electric scooter with brushless DC motor using field-oriented control Digital Twin of an electric scooter

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Jatin Anand; [2021]
    Keywords : ;

    Abstract : A motor control algorithm to control a brushless DC motor has been implemented and tested in this master thesis. Model-based development approach has been applied to implement the entire system that includes the control algorithm (Field-Oriented Control) and the model of a brushless DC motor. READ MORE
