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 Overdamped response Underdamped response Unstable response Undamped response Overdamped response Underdamped response ANSWER DOWNLOAD EXAMIANS APP
Process Control and Instrumentation The characteristic equation for the control system with a closed loop transfer function G₁/1 + G₂ is given by 1 + G₂ = 0.
