  1. 41. Modeling and Control of a PMSM Operating in Low Speeds

    University essay from Linköpings universitet/Fordonssystem

    Author : Robin Helsing; Tobias Sanchez; [2022]
    Keywords : PMSM; BLDC; low speed; EKF; UKF; MPC; Extended Kalman Filter; Unscented Kalman Filter; PI; Control; FOC;

    Abstract : A permanent magnet synchronous motor is a type of motor that is used in several different application areas, not least in an autonomous robots where it is the motor that drives the wheels. Today, many actors choose simulation as a tool to save money and time when product tests are performed. READ MORE

  3. 42. Mitigating SSCI in a hybrid wind and PV farm utilizing PV-STATCOM : A Swedish case study

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Isabelle Löfgren; [2022]
    Keywords : impedance analysis; PV-STATCOM; SSCI; SSO; SSR; sub-synchronous control interaction;

    Abstract : The share of electricity generation in the power system being based on power electronics is increasing, which will impact the system in different ways, such as an increased risk for undesired interactions. An example is doubly fed induction generator (DFIG) based windfarms which have been shown to present negative resistance in (parts of) the sub-synchronous range (i. READ MORE

  4. 43. Multibody modelling of the vibrations in an aircraft engine

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

    Author : Charly Mollet; [2022]
    Keywords : Vibrations; Multibody Modelling; Rolling Bearings; Rotor Dynamics; Reduction Processes; Vibrationer; multikroppsmodellering; rullingslager; rotordynamik; reducktionsprocesser;

    Abstract : During the assembly of aircraft engines, some clearance is left in the rolling bearings mainly to reduce friction. However this clearance might allow the rolling element to vibrate during flight. Indeed, unwanted vibrations called non-synchronous vibrations (NSV) appear on the data recorded by the sensors on some development engines. READ MORE

  5. 44. Eye movement during available Eye Contact, Skewed Visuality and Time Delay in Video Conversation

    University essay from Umeå universitet/Institutionen för psykologi

    Author : Foteini Gkivizini; [2022]
    Keywords : online video call; eye movement; eye tracking; eye contact; online synchronous communication; social breathing; videosamtal online; ögonrörelser; ögonspårning; ögonkontakt; synkron kommunikation online; social andning;

    Abstract : Online conversations via video have nowadays partially replaced face to face contact, and there are some challenges that occur in video conversations, e.g., time delay and the placement of the camera which leads to eliminating the possibility for direct eye contact, and time delay.

  6. 45. Synchronous vs Asynchronous calls and Flow Control for HLA 4

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : David Frisén; [2022]
    Keywords : HLA; Federate Protocol; Synchronous; Asynchronous;

    Abstract : HLA is a standard for distributed simulations where many small simulations connect to each other to create a bigger simulation. As networking technologies have evolved the requirements for the simulations. This includes running certain simulations to communicate over Wide Area, 4G, and 5G networks. READ MORE
