Simulering av clutchservo
Oppgavetekst: clutch_servo.pdf
Tips:
- The table-lookup (for calculating the spring force as a function
of the position or displacement) in the LabVIEW-simulator can be
implemented with the Table Lookup 1D-function which is on the
Simulation Palette in combination with a MathScript-node. Here is an
example: table_lookup_test.vi.
- The mathematical model of the clutch contains three somewhat
complex differential equations. Before you implement the block
diagram, you should rearrange the differential equations into a
state-space model with only the first-order time-derivatives on the
left side of the equations. You can of course implement the model
using integrators together with blocks for the right-side part of the
state-space model, but it may be simpler to express the right-side
part with C-code in a Formula Node. Cf. Section 5.1 in
Introduction to LabVIEW Simulation Module.
- The time-step of the simulator can be set to e.g. 0.001 sec. The
servo is quite quick, so it may be convenient to run the simulator
slower than the real system.
