3 cards from this section. Quick, good the night before a test.
Define steady-state error.
Think about how a system behaves over a long period.
What is K_a in context of control systems?
Consider how a system adjusts to fast changes.
What is the steady-state error formula for a parabolic input?
Focus on how K_a is involved with parabolic inputs.
True or False: A higher K_a results in a higher steady-state error.
Remember what the value of K_a signifies.
You have a control system designed for a robotic arm with K_a = 15. Calculate the steady-state error for a parabolic input and discuss how altering K_a would impact performance.
Use the given formula and reason out the implications of responsiveness.
Propose a design modification to a system where K_a is observed to be decreasing due to wear. Explain how this change would help reduce steady-state error.
Consider ways mechanical reliability can influence control strategies.
