SIMPLORER User Manual V6.0 - FER-a

Defining the Sample Time
You can choose system sample time '0' or a specific value for each block.
5.1 Continuous Blocks
• S-Transfer Function (GS)
• Gain (GAIN)
• Derivative (DIFF)
• Integrator (INTG)
• Memory (DEAD)
• Dead-Time Element (DEAD)
• Delay (GZ)
S-Transfer Function
SIMPLORER 6.0 — Manual 203
The block sequence in subsheets must be defined separately. Open the subsheet and choose
SHEET>DETERMINE BLOCK SEQUENCE. The sequence starts in each subsheet with '1'.
The sampling time must be greater than the minimum time step (HMIN) and less than the
simulation end time (TEND). If the sampling time is defined with «System», the blocks are calculated
with the time step determined by the other modules (circuit, state graph, or equations),
but at least by the maximum time step of integration.
>>Basics>Blocks>Continuous Blocks
The Block represents a continuous transfer characteristic G(s) (Laplace-domain, Laplace-operator
specified as s). Within the dialog you can define numerator and denominator order and
coefficients of the S-Transfer Function.

Dialog Settings
«Numerator»«Order»
Enter a numerical value (non-negative integer with or without unit suffix) in the text box to
define the numerator order of the transfer function. Please note: You cannot define a variable
or expression in this case. Only a number is accepted.
«Numerator»«Coefficient»
Click the «Value» field of the corresponding numerator coefficient B[n] to define a value.
Common parameter types. Enter a numerical value, a variable, or an expression.
«Denominator»«Order»
Type a numerical value (non-negative integer with or without unit suffix) in the text box to
define the denominator order of the transfer function. Please note: You cannot define a variable
or expression in this case. Only a number is accepted.
