Package Modelica.​Blocks.​Types
Library of constants, external objects and types with choices, especially to build menus

Information

In this package types, constants and external objects are defined that are used in library Modelica.Blocks. The types have additional annotation choices definitions that define the menus to be built up in the graphical user interface when the type is used as parameter in a declaration.

Extends from Modelica.​Icons.​TypesPackage (Icon for packages containing type definitions).

Enumeration Modelica.​Blocks.​Types.​Init
Enumeration defining initialization of a block

Information

The following initialization alternatives are available:

NoInit
No initialization (start values are used as guess values with fixed=false)
SteadyState
Steady state initialization (derivatives of states are zero)
InitialState
Initialization with initial states
InitialOutput

Literals

NameDescription
NoInitNo initialization (start values are used as guess values with fixed=false)
SteadyStateSteady state initialization (derivatives of states are zero)
InitialStateInitialization with initial states
InitialOutputInitialization with initial outputs (and steady state of the states if possible)

Enumeration Modelica.​Blocks.​Types.​InitPID
Enumeration defining initialization of PID and LimPID blocks

Information

This initialization type is identical to Types.Init and has just one additional option DoNotUse_InitialIntegratorState. This option is introduced in order that the default initialization for the Continuous.PID and Continuous.LimPID blocks are backward compatible. In Modelica 2.2, the integrators have been initialized with their given states where as the D-part has not been initialized. The option DoNotUse_InitialIntegratorState leads to this initialization definition.

The following initialization alternatives are available:

NoInit
No initialization (start values are used as guess values with fixed=false)
SteadyState
Steady state initialization (derivatives of states are zero)
InitialState
Initialization with initial states
InitialOutput
Initialization with initial outputs (and steady state of the states if possible)
DoNotUse_InitialIntegratorState
Do not use, only for backward compatibility (initialize only integrator state)
