Steady state error- Control system

Click For Summary
SUMMARY

The discussion centers on calculating steady state error in control systems, specifically using the formula Ea(G1+D)G2=C. The equation indicates that the steady state error can be derived from the relationship between the error signal Ea, the system components G1, G2, and the disturbance D. Participants also explore potential contradictions in interpretations of the formula, emphasizing the importance of clarity in control system analysis.

PREREQUISITES
  • Understanding of control system fundamentals

Hello,

I have a question about steady state error.

how can we get to the C?

I think it has to be Ea(G1+D)G2=C
which gives(R-NH)(G1+D)G2 / (1+(G1+D)G2H)=C

Hi,

Is there a contradiction between what you write and what the author writes ?
