  1. 1. Preliminary Design and Conceptual Analysis of an Electrically Actuated Pintle Injector

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Simone Guietti; [2024]
    Keywords : Pintle injector; space propulsion; space engineering;

    Abstract : ”The Eagle has landed”. With this words, astronaut Neil Armstrong, together with astronaut Edwin ”Buzz” Aldrin, confirmed the safe landing on the Moon of the Apollo11 on July 20th, 1969. This achievement would have never been possible without the engineering behind the construction of the Moon lander. READ MORE

  3. 2. Evaluation of electric actuation for fighter aircraft

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Dennis Moliner Pettersson; Anton Nygårds; [2023]
    Keywords : EMA; actuator; actuation; MEA; aircraft; PMSM; SHA;

    Abstract : The tendency of recent years towards electrification of aircraft components and subsys-tems has opened the door for a wider usability of electro-mechanical actuators (EMAs) inthat context. EMAs are already in use in aircraft industries but mainly in civil aviation forsecondary control systems and non-critical applications. READ MORE

  4. 3. Control of an Over-Actuated Vehicle for Autonomous Driving and Energy Optimization : Development of a cascade controller to solve the control allocation problem in real-time on an autonomous driving vehicle

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

    Author : Gianmarco Grandi; [2023]
    Keywords : LTV-MPC Linear Time-Varying Model Predictive Controller ; Trajectory following; Energy consumption; Vehicle stability; Vehicle model; Real-time performance; LTV-MPC Controllo a predizione del modello lineare tempo variabile ; Inseguimento di traiettoria; Consumo energetico; Stabilità del veicolo; Modello del veicolo; Prestazioni in tempo reale; LTV-MPC Linjär tidsvariabel modellförutsägande styrning ; spårföljning; energiförbrukning; fordonsstabilitet; fordonsmodell; prestanda i realtid;

    Abstract : An Over-Actuated (OA) vehicle is a system that presents more control variables than degrees of freedom. Therefore, more than one configuration of the control input can drive the system to a desired state in the state space, and this redundancy can be exploited to fulfill other tasks or solve further problems.

  5. 4. Enhancing Sensing in Nanoscale: Investigation of Smart Nanomechanical Cantilever Array

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Hiruy Michael Weldegiorgish; [2022]
    Keywords : Cantilever; AFM; Biosensor; Piezoresistive sensor; Piezoelectric actuator; Kantilever; AFM; Biosensor; Piezo -resistorer; Piezo-elektiska pådrivare;

    Abstract : In this report, a novel smart nanocantilever with self-deflection sensor using embedded piezo-resistor and self-actuation using integrated piezo-electric actuator is proposed, designed and simulated to enable highly sensitive label free biosensor and ultra-short cantilever probe for AFM applications. The smart nanocantilever comprises of a triangular Si3N4 nanocantilever (10µm long, 400nm width and 100nm thickness) connected to a multi-layer support structure (Si3N4 (100nm)/PZT (100nm)) having n-type silicon piezo resistor (7µm long ,2µm width and 20nm thickness) embedded in the Si3N4 layer in both the support structure and nanocantilever.
