  1. 6. Structural Investigations of Novel Heliostat Designs based upon the Hydraulic Infinite Linear  Actuator (HILA)

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Venkata Nikhil Nandigama; [2021]
    Keywords : Structural Analysis; Heliostat; Mechanics; Topology optimization; Finite element methods; concentrated solar power; renewable energy.;

    Abstract : A heliostat is a device that reflects the sun’s rays to a stationary object. There are two different types of heliostat serial and parallel type. The most used is the serial type of heliostat with Azimuthal-Elevation(Az-El) drive. READ MORE

  3. 7. Efficiency verification of an electromechanical linear actuator

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

    Author : Ingela Råberg; [2021]
    Keywords : Efficiency; Linear actuator; Modelling; Romax; Linjärt ställdon; Modellering; Romax; Verkningsgrad;

    Abstract : Cascade Drives has developed an electromechanical linear actuator with a patented feature which allows for load sharing between multiple pinions interacting on the same rack. This arrangement has proven resilient for shock loads, and allows for compact gearbox designs with very high load rating. READ MORE

  4. 8. Current Control and Modelling of an Inspiration Valve

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Astrid Lindstedt; [2021]
    Keywords : Current Servo; Cascade Control; Solenoid Model; Ventilator; Strömregulator; Kaskadreglering; Solenoid modell; Respirator;

    Abstract : An analog current servo of an intensive care ventilator is being developed at Getinge in Stockholm. The current servo is used to control the output gas flow of an inspiration valve to a patient’s lungs. The ventilator’s control system is in a cascade design of two closed-loops, of which the current servo is the controller for the inner loop. READ MORE

  5. 9. Mechanical Design, Analysis, and Manufacturing of Wind Tunnel Model and Support Structure

    University essay from KTH/Lättkonstruktioner

    Author : Sara Ghika; [2021]
    Keywords : Aerospace; wind tunnel testing; lightweight structures; UAV; Mekanisk Design; Analys och Tillverkning av Vindtunnelmodell och Stödstruktur;

    Abstract : This volume covers the phases from design to manufacturing of a wind tunnel test support structure for a conceptual blended wing-body UAV designed by KTH Green Raven Project students. The innovative aircraft design demonstrates sustainability within aviation by utilizing a hybrid electric-fuel cell propulsion system. READ MORE

  6. 10. Learning-Based Motion Planning and Control of a UGV With Unknown and Changing Dynamics

    University essay from Linköpings universitet/Reglerteknik

    Author : Åke Johansson; Joel Wikner; [2021]
    Keywords : machine learning; model predictive control; motion planning; Bayesian linear regression; motion primitives; input sampling; hybrid A*;

    Abstract : Research about unmanned ground vehicles (UGVs) has received an increased amount of attention in recent years, partly due to the many applications of UGVs in areas where it is inconvenient or impossible to have human operators, such as in mines or urban search and rescue. Two closely linked problems that arise when developing such vehicles are motion planning and control of the UGV. READ MORE
