1. 1. IC-Engine Source Characterisation and exhaust system simulations

   Master-uppsats, KTH/Marcus Wallenberg Laboratoriet MWL

   Författare :Pontus Gräsberg; [2021]
   Nyckelord :IC-engine; source characteristics; Multiload method; one-port source; exhaust system; Bränslemotor; källkarakterisering; avgassystem;

   Sammanfattning : To be able to predict the sound pressure level emitted by a exhaust system one must be able to describe the source. The source in the form of an engine can linearly be described as a source strength and a source impedance. An IC-engine can acoustically have a non-linear part meaning that the source characteristics have a dependency on the load. LÄS MER

3. 2. Reaction Wheel Stabilized Stick

   Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Pontus Gräsberg; Bill Lavebratt; [2019]
   Nyckelord :Mechatronics; Reaction wheel; Inverted pendulum; State space; Control theory.;

   Sammanfattning : Control theory can be used to make an unstable system stable. This thesis seeks to do this, where the system is a two DOF inverted pendulum with reaction wheels for stabilisation. The thesis also seeks to answer what is most important for making it stabilize for a longer period of time. LÄS MER
