When Kp is increased, the error is reduced at constant rate, but the transient can also be adversely affected. Adverse
effects can be a longer transient with stronger oscillations due to the damping reduction, or even instability. This is
shown in the figure below:

As soon as an input variance occurs (Error), an
output variance occurs. The variation rate is
proportional to the error magnitude.
Sets the tuning point (eliminates the offset from
the proportional action).
