Closed-loop transfer function

The closed-loop transfer function is a mathematical representation of the relationship between the output and input of a control system when feedback is applied. It describes how the system behaves when a portion of the output is fed back into the system input to regulate the behavior of the output. In the context of control systems, the closed-loop transfer function can be defined as follows: 1. **Open-Loop Transfer Function**: It is the transfer function of the system when no feedback is applied.
