The error signal in a negative feedback control system is the difference between the input and the feedback signal.
The transfer function for error is given by:
Where:
R(s) = Reference Input,
E(s) = Error Signal,
G = Forward Path Gain,
H = Feedback Path Gain.
Calculation:
Given a negative feedback system, the output is fed back through H and compared with input R(s).
The error signal E(s) is:
With unity feedback or feedback factor H, and forward gain G, the output becomes:
Hence, the error signal is:
