4. 23. Cross coupling in a two-axis control system for stabilized platforms

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Bill Lavebratt; [2022]
   Nyckelord :MIMO; Modeling; Two-axis gimbal system; Decoupler; Inner loop disturbance compensation; Control theory.;

   Sammanfattning : Inertial stabilized platforms consisting of a two-axis gimbal assembly are often modelled as two independent SISO systems, describing the dynamics of the elevation axis and the azimuth axis respectively. In reality the state of the elevation channel and the state of the azimuth channel affect each other. LÄS MER

5. 24. Deep Neural Networks for dictionary-based 5G channel estimation with no ground truth in mixed SNR scenarios

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Matteo Ferrini; [2022]
   Nyckelord :5G; Channel Estimation; Sparse Linear Inverse Problem; Approximate Message Passing; Neural Networks; 5G; kanaluppskattning; sparsamt linjärt inversproblem; approximativ meddelandeöverföring; neurala nätverk;

   Sammanfattning : Channel estimation is a fundamental task for exploiting the advantages of massive Multiple-Input Multiple-Output (MIMO) systems in fifth generation (5G) wireless technology. Channel estimates require solving sparse linear inverse problems that is usually performed with the Least Squares method, which brings low complexity but high mean squared error values. LÄS MER

7. 25. Control System Simulator for MIMO Tank Level using Self-tuning PID-Fuzzy Adaptive Controller

   Magister-uppsats, Högskolan i Gävle/Avdelningen för elektroteknik, matematik och naturvetenskap

   Författare :Sinan Ibrahim; [2022]
   Nyckelord :;

   Sammanfattning : According to Oxford dictionary, the word intelligence is derived fromintellect, which is the ability of knowing, reasoning and understanding.Intelligent behaviour is thus the ability to reason, plan and learn, which in turnrequires access to knowledge. LÄS MER
