Process Control and Instrumentation In a second order under damped system, the Overshoot (which is a measure of how much the response exceeds the ultimate value) increase with the decrease of damping co-efficient e None of these Time required for the response of first reach its ultimate value is called the response time Decay ratio (which is the ratio of the sizes of successive peaks) is equal to the reciprocal of overshoot Overshoot (which is a measure of how much the response exceeds the ultimate value) increase with the decrease of damping co-efficient e None of these Time required for the response of first reach its ultimate value is called the response time Decay ratio (which is the ratio of the sizes of successive peaks) is equal to the reciprocal of overshoot 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 Undamped response Overdamped response Underdamped response Unstable response Undamped response Overdamped response Underdamped response ANSWER DOWNLOAD EXAMIANS APP
