FOPDT – First order plus dead-time model

Block SymbolLicensing group: STANDARD
PIC

Function Description
The FOPDT block is a discrete simulator of a first order continuous-time system with time delay, which can be described by the transfer function below:

P(s) = k0 tau s + 1 edels

The exact discretization at the sampling instants is used for discretization of the P(s) transfer function. The sampling period used for discretization is equivalent to the execution period of the FOPDT block.
