Question 1.
What is steady-state error?
Show hintHide hint
Consider its definition in terms of system behavior.
Question 2.
Define Kp in control systems.
Show hintHide hint
Think of it in terms of different inputs.
3Question 3.
What does steady-state error quantify?
- Difference between input and output
- Difference between desired and actual output
- Difference between temporary and permanent output
Show hintHide hint
Think about what happens as time approaches infinity.
4Question 4.
True or False: The position error constant Kp is used for ramp inputs.
- True
- False
Show hintHide hint
Consider which error constants correlate to which input types.
Question 5.
A control system's stability is compromised if the steady-state error for a ramp input is too high. Discuss how Kp, Kv, and Ka can be modified to optimize the steady-state behavior for various inputs. Provide reasoning for your suggestions.
Show hintHide hint
Consider the relationships between input types and their corresponding error constants.
Question 6.
Given a second-order control system with transfer function G(s) = 10/(s^2 + 4s + 10), determine Kp, Kv, and Ka and hence compute the steady-state errors for step, ramp, and parabolic inputs.
Show hintHide hint
Apply limit evaluations for error constants from the transfer function to set the context for steady-state responses.
