  1. 6. Impact of Time Synchronization Accuracy in Integrated Navigation Systems

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

    Author : Hemanth Ram Kartik Bommakanti; [2019]
    Keywords : Real-Time Solution; Time Synchronization; Integrated Navigation System; Global Navigation Satellite System; Inertial Measurement Unit; Realtidslösning; tidssynkronisering; integrerat navigationssystem; globalt satellitbaserat navigationssystem; tröghetsmätningsenhet;

    Abstract : Global Navigation Satellite System/Inertial Measurement Unit (GNSS/IMU) Integrated Navigation Systems (INS) integrate the positive features of GNSS and IMU for optimal navigation guidance in high accuracy outdoor navigation systems, for example using Extended Kalman Filter (EKF) techniques. Time synchronization of IMU data with precise GNSS based time is necessary to accurately synchronize the two systems. READ MORE

  3. 7. Trajectory Planning for Autonomous Vehicles and Cooperative Driving

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Benjamin Nordell; [2016]
    Keywords : ;

    Abstract : Autonomous vehicles have been the subject of intense research, resulting in many of the latest cars being at least partly self driving. Cooperative driving extends this to a group of vehicles called a platoon, relying on com-munication between the vehicles in order to increase safety and improve the ˛ow of tra°c. READ MORE

  4. 8. Estimation and Compensation of Load-Dependent Position Error in a Hybrid Stepper Motor

    University essay from Linköpings universitet/Reglerteknik

    Author : Anton Ronquist; Birger Winroth; [2016]
    Keywords : Adaptive Notch Filter; Back-EMF; Electric Motor Position Control; Error Modelling; Field-Oriented Control; Hybrid Stepper Motor; Kalman Filter; Load Angle; Magnetic Rotary Position Sensor; Sensorless Control; Sliding Window Discrete Fourier Transform; Stall Detection and Prediction.;

    Abstract : Hybrid stepper motors are a common type of electric motor used throughout industry thanks to its low-cost, high torque at low speed and open loop positioning capabilities. However, a closed loop control is often required for industrial applications with high precision requirements. READ MORE
