P element
As P-member is referred to a LZI - transmission member in the control engineering , which is a proportional having transmission characteristics. The associated functional relationship in the time domain is
- ,
so that the complex transfer function in the image area takes the form
Has. Here, K, K> 0 denotes the transfer constant or the gain factor.
Bode diagram
The P element is . Therefore, the following applies to the amplitude and phase response in the Bode diagram :
The amount characteristic is therefore a straight line at a distance of K dB from the 0 dB line. The phase characteristic is a constant 0 °.
Step response
The step response of the P element describes a unit step with step height K.
Locus
The locus ( ) of the P element lies for all ω on the positive real axis at point K.
