In a closed loop system, the process to be controlled is an integrating process with transfer function l/2s. The controller proposed to be used in an integral controller with transfer function 1/T₁s.

• A. Underdamped response
• B. Undamped response
• C. Overdamped response
• D. Unstable response

Answer: (A)
