2.1 The Laplace Transform. The Laplace transform underpins classic control theory.32,33,85 It is almost universally used. An engineer who describes a “two-pole filter” relies on the Laplace transform; the two “poles” are functions of s, the Laplace operator. The Laplace transform is defined in Equation 2.1. In Section 4.3.1 we have defined the transfer function of a linear time invariant continuous-timesystem. The system transfer function is the ratio of the Laplace transform of the system output and the Laplace transform of the system input under the assumption that the system initial conditions are zero. This transfer function in Given a process with an input signal, a transfer function and an output, it is important to note that the transfer function in and of itself doesn't tell you anything about the input signal. What the transfer function tells you is the relationship between the input and the output (i.e. what the process will do to ANY input).Forward path and feedback are represented by Laplace transforms, so multiplication of transfer functions can take the place of time-domain convolution integrals.

The integrator can be represented by a box with integral sign (time domain representation) or by a box with a transfer function \$\frac{1}{s}\$ (frequency domain representation). I'm not entirely sure i understand why \$\frac{1}{s}\$ is the frequency domain representation for an integrator. Laplace transforms comes into its own when the forcing function in the differential equation starts getting more complicated.
