Making Block Diagram
  • Draw input and output
  • Go backwards from the output set integrators in
  • Set in the summation(Try to make it sum a
    physical size. Ex force N)
  • Connect input and feedback
  • relations

Simulation Exercise
Input the DC motor, in Simulink and make a M-file
with the motor data. Test a step response.

Exercise MM2 Slæde
  • Tegn free body diagrammer for systemt.
  • Opstil bevægelses ligninger for systemerne.
    (passende til de enkelte free body diagrammer)
  • Hvilken antagelser ville lette beregningerne
    betydelig under
  • sammensættelse af systemet?
  • 4. Tegn blokdiagrammet.
  • 5. Hvilken orden er det mekaniske system? (Input
    aksel ved motor og output er positionen af
    slæden)
  • Opstille overførringsfunktion, motor spænding til
    position af slæden. Er det principielt muligt?
    (Måske er det nødvendig at laplace
    transformerede)
  • Hvilken ordens system er dette? Input motor
    spænding og output er hastighed af slæden.
