  1. 21. Development of Test Methodology for Electromechanical Linear Actuators

    University essay from Uppsala universitet/Signaler och system

    Author : Isak Linder; [2022]
    Keywords : Electromechanical; linear actuator; test methodology; test rig; rack and pinion; transport delay; latency; spring mass damper; load cell; load force; load unit; test unit; DUT; PID; PID control; control mechanics; cogging torque; torque; flex; stiffness; current saturation; torque control;

    Abstract : This master thesis aims to develop a test methodology for electromechanical linear actuators. A linear actuator acts as a linear motor, converting a power source to linear motion. The electromechanical linear actuator in this project has an electric motor as its power source and uses a rack and pinion system to transfer that power to linear motion. READ MORE

  2. 22. Adaptive Systems to Reduce the Material Cost of Structures

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Erik Lundin; [2022]
    Keywords : Adaptive; structure; material economy.; Technology and Engineering;

    Abstract : Adaptive structures adapt to the changing circumstances in their environment using sensors and actuators, they may for example change their shape to be optimised for a specific load case when that load case is present. The building industry need to reduce its climate impact, low-carbon solutions are in demand. READ MORE

  3. 23. Data-driven cyberattack detection for microgrids

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

    Author : Jiaying Mao; [2022]
    Keywords : Cyberattack detection; Deep learning network; Microgrid; Smart inverter; Cyber-physical system; Distributed system; Detektering av cyberattacker; Djupinlärning nätverk; Microgrid; Smart växelriktare; Cyberfysiska system; Distribuerade system;

    Abstract : Microgrids are undergoing higher penetrations of renewables and associated power electronics, along with precise and sophisticated control and communication networks. However, such cyber-physical systems might suffer from potential cybersecurity threats and inherent low inertia. READ MORE

  4. 24. Requirements and Analysis of an Overload Protection Mechanism for an Electromechanical Linear Actuator

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Mats Vesterberg; [2022]
    Keywords : EMA; Electromechanical Actuator; Linear Actuator; Shock load; Protection mechanism; Elektromekaniska ställdon; Linjära ställdon; Shocklaster; Överlastskydd;

    Abstract : Cascade Drives specializes in high-performance electromechanical linear actuators (EMA). The company has developed a range of linear rack and pinion actuators based on a patented load distribution technique that allows multiple pinions to interact with a single gear rack. READ MORE

  5. 25. Weight prediction of flight control subsystem

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Joel Lundahl; [2022]
    Keywords : Aeronautical engineering; aircraft; fighter jet; flight control system; FCS; weight prediction; early weight prediction; hydraulic system; control surfaces; actuator; subsystem; weight estimation; Flygteknik; flygplan; militärflygplan; stridsflygplan; styrsystem; viktprediktering; tidig viktprediktering; hydraulsystem; styrroder; styraktuatorer; aktuator; delsystem; viktuppskattning; metod;

    Abstract : A common dilemma in aircraft design is the importance of knowing weight characteristics at early design stages, since sizing of many important components is dependent on these. Yet precise weight data cannot be determined until the aircraft and its subsystems have been designed in detail. READ MORE
