Challenge Problems
Push your limits with advanced challenges
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.
💡 Hint: Consider the relationships between input types and their corresponding error constants.
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.
💡 Hint: Apply limit evaluations for error constants from the transfer function to set the context for steady-state responses.
