Question 5.
Given a closed-loop control system with a transfer function G(s)=K/(τs + 1) and a feedback H(s)=1, derive the overall system response when subjected to a step input.
Show hintHide hint
Focus on applying the feedback loop concept correctly.
Question 6.
Explain how altering the parameter τ in the transfer function affects the stability and transient response of the system.
Show hintHide hint
Think about the relationship between time constants and response behavior.
