s is an operator. A transfer function is a shorthand for a differential equation that describes
the behavior of a linear system. You can use a transfer function almost directly to get a frequency response of a system by substituting values into s, but to get a response to a signal in the time domain, you need to simulate the system, or solve the inverse Laplace transform of the output signal.
I have this transfer function of an open-loop control system:
H(s) / Qi(s) = R / A x Rs + 1
I'm not sure which method I should use, whether to substitute values into s or do inverse Laplace transform on output signal.
Which would you suggest and what is the answer to that solution?
