Block diagram for a simulation of the analog meter modelModeling – P.L. Kvq here is the open-loop gain, Kvq = Kqv-1 Similar motion plan as proposed in first lab Saturation block models the limited voltage range of the AO in the myDAQ You can construct a model in the Control & Simulation Loop using blocks, formula nodes, and MathScript, as shown before. But you can also construct transfer function (TF) models. Look under: Simulation->Continuous to find Transfer Function. You need to define the TF as shown on next slide. ME 144L – Prof. R.G.

The “CD Construct Transfer Function Model” can be used to define models of the form we’ve constructed: Kθ / vωn2 = 2 2 vin s + 2ζωn s + ωn θn Define the coefficients in symbolic form in ascending order on front panel In the variables cluster, you can assign numerical values to each symbolic parameter that is used in the symbolic numerator and denominator expressions.
