Process Control and Instrumentation For a feed back control system to be stable, the Roots of the characteristic equation should be real Poles of the closed loop transfer function should lie in the right half of the complex plane Poles of the closed loop transfer function should lie in the left half of the complex plane Bode plots of the corresponding open loop transfer function should monotoni-cally decrease Roots of the characteristic equation should be real Poles of the closed loop transfer function should lie in the right half of the complex plane Poles of the closed loop transfer function should lie in the left half of the complex plane Bode plots of the corresponding open loop transfer function should monotoni-cally decrease ANSWER DOWNLOAD EXAMIANS APP
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 Underdamped response Overdamped response Undamped response Unstable response Underdamped response Overdamped response Undamped response ANSWER DOWNLOAD EXAMIANS APP
