  1. 1. Signal-filtration methodology for estimation of fuel level

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Alexander Örneskans; [2018]
    Keywords : fuel level estimation; fuel level prediction;

    Abstract : Knowing how much fuel there is in a car is important for a predictable driving experience. Such knowledge will dictate how a person drives, when to refuel and how long they can drive. However unprocessed fuel level signals are highly noisy and therefore misleading. READ MORE

  2. 2. Control of a Multivariable Lighting System

    University essay from Linköpings universitet/Reglerteknik

    Author : Axel Halldin; [2017]
    Keywords : Cotrol Allocation; lighting system; MIMO control; multivariable control; light system; recursive least square; RLS; model predictive control; MPC; LQG; static control; non-dynamic control;

    Abstract : This master’s thesis examines how a small MIMO lighting system can be identified and controlled. Two approaches are examined and compared; the first approach is a dynamic model using state space representation, where the system identification technique is Recursive Least Square, RLS, and the controller is an LQG controller; the second approach is a static model derived from the physical properties of light and a feedback feed-forward controller consisting of a PI controller coupled with a Control Allocation, CA, technique.

  3. 3. AN ADAPTIVE CONTROL SYSTEM BASED ON PID, I2PD AND RLS, A SIMULATED DESIGN FOR UAVS

    University essay from Mälardalens högskola/Akademin för innovation, design och teknik; Mälardalens högskola/Akademin för innovation, design och teknik

    Author : Johan Gärtner; Philip Johansson; [2017]
    Keywords : RLS; PID Controller; UAV; quadrotor; adaptive control; I2PD; simulation;

    Abstract : During this master thesis an adaptive control system for angular velocity was developed. The approach focuses on radio controlled quadrotors and thereby targets a computational efficient solution. The adaptation is divided into two steps. READ MORE

  4. 4. Passive Inter-modulation Cancellation in FDD System

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Fan Chen; [2017]
    Keywords : Technology and Engineering;

    Abstract : Passive inter-modulation (PIM) shows up when two or more RF signals are mixed together via the nonlinear passive devices. With the rapid development and expansion of the wireless com-munication networks, PIM is recognized as one of the most critical issues. READ MORE

  5. 5. Robust Echo-Cancellation for Simple VoIP-Applications in Embedded Systems

    University essay from Linköpings universitet/Kommunikationssystem

    Author : Anton Eriksson; [2015]
    Keywords : VoIP; Adaptive Filtering; Signal Processing;

    Abstract : Voice over IP (VoIP) is the group of techniques for delivering voice communications over Internet Protocol (IP) networks. It has mainly served as the possible substitution for regular PSTN over the last decades, but has recently gained an increased interest in various areas such as alarm applications and customer service.
