  1. 1. Comparison of Level Control Strategies for a Flotation Series in the Mining Industry

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Frida Norlund; [2022]
    Keywords : Technology and Engineering;

    Abstract : Separating valuable minerals from waste rock is an important step in the production of metals. This is for copper ore done through a process called flotation. A flotation series consists of tank cells in series where the minerals are collected in a froth on top of the cells. READ MORE

  3. 2. Trajectory Tracking for Automated Guided Vehicle

    University essay from Linköpings universitet/Reglerteknik

    Author : Anton Holgersson; Johan Gustafsson; [2021]
    Keywords : AGV; PID; Proportional-Integral-Derivative; LQ; Linear Quadratic; Controller; MIMO; Error Model; Simulink; Dead Time;

    Abstract : The purpose of this thesis is to investigate different control strategies on a differential drive vehicle. The vehicle should be able to drive in turns at high speed and slowly when it should park next to a charger. In both these cases, good precision in both orientation and distance to the path is important. READ MORE
