What is a  Transfer Function?

Transfer Function Definition

A transfer function is defined as the ratio of the Laplace transform of a system’s output to the input, assuming initial conditions are zero.

Utilization of Block Diagrams

Block diagrams simplify complex control systems into manageable components, making it easier to analyze and derive transfer functions.

Understanding Poles and Zeros

Poles and zeros critically influence a system’s behavior by indicating points where the transfer function respectively becomes infinite or zero.

Laplace Transform in Control Systems

Laplace transform is essential for representing all types of signals in a uniform format, aiding in the mathematical analysis of control systems.

Impulse Response Insight

The output from an impulse input reveals the transfer function, illustrating the direct relationship between a system’s input and output.
