Proportional control

As a P-element is called an LTI transfer member in control engineering, which has a proportional transfer behavior. The corresponding functional relationship in the time domain is

So that the complex transfer function in the image domain in the form

Has. Herein, K, K > 0, the propagation constant and the amplification factor.

Bode diagram

Is the P -element. Hence, in the amplitude and phase response in the Bode diagram:

The amount characteristic is therefore a straight line at a distance KdB from the 0 - dB contours. The phase characteristic is a constant 0 °.

Step response

The step response of the P element describes a unit step with the jump height K.

Locus

The locus () of the P element is for all ω on the positive real axis at the point K.
