What is the reason for not giving very High Proportional Gain Kp in PID Controller?..

Answer / deepti

A high proportional gain results in a large change in the
output for a given change in the error. If the proportional
gain is too high, the system can become unstable (see the
section on loop tuning). In contrast, a small gain results
in a small output response to a large input error, and a
less responsive (or sensitive) controller. If the
proportional gain is too low, the control action may be too
small when responding to system disturbances.

Great answer Deepti

and also with increasing the Kp gain we increase the MAX.
OVEERSHOOT of the process which may harm the process and
