How does cascading an integral controller in the forward path of a control system affect the relative stability (RS) and the steady-state error of that system?
A. RS and SSE are increased
B. RS is reduced nut SSE is increased
C. RS is increased but SSE is reduced
D. RS and SSE are reduced
Answer:D

A. RS and SSE are increased B. RS is reduced nut SSE is increased C. RS is increased but SSE is reduced D. RS and SSE are reduced
Explanation: Integral Controller acts like a low pass filter. It reduces the stability as well as steady state error.
