Process Control and Instrumentation 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. When a step change in set point is applied to such a closed loop system, the controlled variable will exhibit Unstable response Undamped response Underdamped response Overdamped response Unstable response Undamped response Underdamped response Overdamped response ANSWER DOWNLOAD EXAMIANS APP
