Modelica.Clocked.BooleanSignals.NonPeriodic

Library of blocks that operate on periodically and non-periodically clocked signals

Information

Extends from Modelica.Icons.Package (Icon for standard packages).

Package Content

Name	Description
BooleanChange	Indicate Boolean signal changing
UnitDelay	Delay the clocked input signal for one sample period
FractionalDelay	Delay the clocked input signal for a fractional multiple of the sample period
ClockToBoolean	Block to translate clock signals to continuous Boolean events (each time the input clock ticks a rising Boolean output edge is produced).

Modelica.Clocked.BooleanSignals.NonPeriodic.BooleanChange

Indicate Boolean signal changing

Information

This block is a synchronous version of Modelica.Blocks.Math.BooleanChange. It uses previous instead of the implicit pre of change to set the Boolean output y to true when the boolean input u changed. Thus, it's logic is:

if firstTick() then
  y = false;
else
  y = not (u == previous(u));
end if;

This block might be superfluous and replaced by Modelica.Blocks.Math.BooleanChange when the semantics of change are relaxed and well-defined for clocked discrete-time partitions.

Extends from Clocked.ClockSignals.Interfaces.ClockedBlockIcon (Basic graphical layout of block where at least one input or output is a clocked variable).

Connectors

Modelica.Clocked.BooleanSignals.NonPeriodic.UnitDelay

Delay the clocked input signal for one sample period

Information

This block describes a unit delay:

// Time domain description
   y(ti) = previous(u(ti))

// Discrete transfer function
           1
   y(z) = --- * u(z)
           z

that is, the output signal y is the input signal u at the previous clock tick. At the first clock tick, the output y is set to parameter y_start.

Extends from Clocked.BooleanSignals.Interfaces.PartialClockedSISO (Block with clocked single input and clocked single output Boolean signals).

Parameters

Connectors
