Note 1 to entry: The transfer function of an ideal proportional plus derivative element is given by

$\frac{V\left(s\right)}{U\left(s\right)}={K}_{\text{\Rho}}\cdot \left(1+{T}_{\text{d}}\cdot s\right)$

where

T_{d} | is the rate time; |

s | is the complex variable of the Laplace transform; |

U(s) | is the input transform; |

V(s) | is the output transform. |
