MDL – Process model

Block SymbolLicensing group: STANDARD

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

F (s) = \frac{K_{0} e^{- D s}}{(τ_{1} s + 1) (τ_{2} s + 1)},

where $K_{0} > 0$ is the static gain k0, $D \geq 0$ is the time-delay del and $τ_{1}, τ_{2} > 0$ are the system time-constants tau1 and tau2.

Input

u	Analog input of the block $⊙$ 0.0	Double (F64)

Output

y	Analog output of the block	Double (F64)

Parameters

k0	Static gain $⊙$ 1.0	Double (F64)
del	Dead time [s] $⊙$ 0.0	Double (F64)
tau1	The first time constant $⊙$ 1.0	Double (F64)
tau2	The second time constant $⊙$ 2.0	Double (F64)
nmax	Size of delay buffer (number of samples) for the time delay del. Used for internal memory allocation. $↓$ 10 $↑$ 10000000 $⊙$ 1.00E+03	Long (I32)
