   Sammanfattning : Having a accurate model of a system is essential for many applications today, especially those related to advanced process control. When executing a project often a lot of time is spent performing experiments on the real system to estimate a model. LÄS MER

5. 4. 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

7. 5. Controller Design for a Gearbox Oil ConditioningTestbed Through Data-Driven Modeling

   Master-uppsats, KTH/Maskinkonstruktion (Inst.)

   Författare :Charles Brinkley IV; Chieh-Ju Wu; [2022]
   Nyckelord :Gearbox; oil conditioning system; system identification; data-driven modeling; pole placement; PID; Växellåda; oljekonditioneringssystem; systemidentifiering; datadriven modellering; polplacerings; PID;

   Sammanfattning : With the exponential development of more sustainable automotive powertrains, new gearbox technologies must also be created and tested extensively. Scania employs dynamometer testbeds to conduct such tests, but this plethora of new and rapidly developed gearboxes pose many problems for testbed technicians. LÄS MER
