Week 05
Steady-State Error
I follow the saved course materials and calculations from modeling through stability, root locus, and frequency response.
What I connect in this unit
Steady-state error depends jointly on feedback system type and reference shape. The number of open-loop poles at the origin changes step and ramp tracking, and error constants connect that structure to the final-value result.
Concept map
- System type
- Error constants
- Step and ramp inputs
- Final value theorem
Technical anchor
For unity feedback, start with ess=lim(s→0) sE(s), then apply Kp=lim G(s) or Kv=lim sG(s) according to the input. The final value theorem is valid only when the required closed-loop poles are stable.
How I review it
Form error expressions for step and ramp inputs on the same loop, then check that the system-type rule and direct limit calculation agree.
