MDLI – Process model with input-defined parameters

Block SymbolLicensing group: STANDARD
PIC

Function Description
The MDLI block is a discrete simulator of continuous-time system with transfer function

F(s) = K0eDs (τ1s + 1)(τ2s + 1),

where K0 > 0 is the static gain k0, D 0 is the time-delay del and τ1,τ2 > 0 are the system time-constants tau1 and tau2. In contrary to the MDL block the system is time variant. The system parameters are determined by the input signals.

Inputs
