Properties of Transfer Function Models 1. Steady-State Gain The steady-state of a TF can be used to calculate the steady-state change in an output due to a steady-state change in the input. For example, suppose we know two steady states for an input, u, and an output, y. Then we can calculate the steady-state gain, K, from: 21 21 (4-38) yy K uu ... A transfer function is a differential equation that is represented in the s-domain rather than the time domain. And since our code is going to execute in the time domain, we will want to get back to the differential equations with the inverse Laplace transform. For example, we can multiply out the numerator and denominator and take the inverse ...
