    Nyckelord :Iterative feedback tuning; Iterative learning control; high precision motion control; Iterative methods for disturbance supression;

    Sammanfattning : Moore’s law states that the number of transistors in an Integrated Circuit (IC) doubles every two years. Ever-increasing performance in mask writing machinery is therefore required being the first step in the manufacturing process. Many factors affect the quality of the end product, with the motion control system playing an important role. LÄS MER

  5. 4. Automating the Process of Measuring Chemical Substances in Samples : Using a Motorised Sampling Platform

    Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Anton Augustsson; Fredrik Engstrand; Fahad Rami Jamil; Johannes Liljedahl; Robert Martinis; [2022]
    Nyckelord :controller; pyvisa; visa; sample platform; sampling platform; motor; conex-cc; qt;

    Sammanfattning : Performing measurements of samples that contain chemical substances is a time consuming task if the measurement instruments are small and require high precision. A single measurement session can often contain a large amount of samples, which is why it is crucial to automate this process. LÄS MER
