Dynamic Error Coefficient Method
This method is also called as Generalized Error Coefficient Method and Error Series Method.
It gives variation of error as function of time.
It can be determined for any input other than standard test input signals.
Generalized error coefficient equation:
𝐾_𝑛=lim(𝑠→0) (ⅆF_1 (𝑠))/ⅆ𝑠)
