1. 1. Construction and Control of a 3-axisAutomated Liquid Sampling UnitUtilizing Hybrid Stepper Motors

   University essay from KTH/Mekatronik och inbyggda styrsystem

   Author : Arvid Bergvall; Pontus Lundman; [2023]
   Keywords : Mechatronics; Gantry; Stepper motor; Control; Linear Quadratic Regulator; Adaptive LQI; PID; Mekatronik; Gantry; Stegmotor; Reglerteknik; LQR; Adaptiv LQI; PID;

   Abstract : High accuracy autonomous positioning systems are becoming increasingly important in today’s chemical industry because they can obtain precise experiment results automatically and hence allow lab technicians to focus on other tasks concurrently. One time consuming process is the process of sampling chemical test results into the correct container, especially when the tests are many and infrequent. 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. Simulation and time-series analysis for Autonomous Emergency Braking systems

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

   Author : Zhiying Xu; [2021]
   Keywords : Autonomous Driving AD ; CARLA; Autonomous Emergency Braking AEB ; Deep Learning; Time-series analysis; Autonom körning; CARLA; Autonomt nödsystem; Djup lärning; Tidsföljder;

   Abstract : One central challenge for Autonomous Driving (AD) systems is ensuring functional safety. This is affected by all parts of vehicle automation systems: environment perception, decision making, and actuation. READ MORE

5. 4. Model-Predictive Control of Gas Exchange in a Gasoline Engine

   University essay from Linköpings universitet/Fordonssystem

   Author : George Jajji; [2021]
   Keywords : Control Engineering; Model Predictive Control; MPC; Gasoline Engine; Gas Exchange;

   Abstract : The process to induct air into engine cylinders, via the air inlet system and cylin-der port valves, is referred to as the "gas-exchange". Control is achieved by theturbo-charger, the intake throttle plate and the variable valve timing (VVT) sys-tem. These actuation systems traditionally use separate control with indepen-dent SISO feedback. READ MORE

6. 5. Quantifying Middle Frequency Transient Currents in Power Consuming Devices

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Alex Lundvall; Vincent Sollie; [2021]
   Keywords : ;

   Abstract : The complexity of electrical systems present in vehicles is continuously rising and the number of interconnected electrical devices is growing during the strive for optimization and reaching higher efficiency levels. Actuation of said devices have the possibility of injecting voltage and current harmonics into the system, thus negatively affecting neighbouring devices. READ MORE
