Specify and assign priorities to the sample times that this model implements.
Category: Solver
No Default
Enter an Nx3 matrix with rows that specify the model's discrete sample time properties in order from fastest rate to slowest rate.
Faster sample times must have higher priorities.
[period, offset, priority]
period | The time interval (sample rate) at which updates occur during the simulation. |
offset | A time interval indicating an update delay. The block is updated later in the sample interval than other blocks operating at the same sample rate. |
priority | Execution priority of the real-time task associated with the sample rate. |
See Specify Sample Time for more details and options for specifying sample time.
[[0.1, 0, 10]; [0.2, 0, 11]; [0.3, 0, 12]]
Declares that the model should specify three sample times.
Sets the fundamental sample time period to 0.1 second.
Assigns priorities of 10, 11, and 12 to the sample times.
Assumes higher priority values indicate lower priorities — the Higher priority value indicates higher task priority option is not selected.
If the model's fundamental rate differs from the fastest rate specified by the model, specify the fundamental rate as the first entry in the matrix followed by the specified rates, in order from fastest to slowest. See Purely Discrete Systems.
If the model operates at one rate, enter the rate as a three-element vector in this field — for example, [0.1, 0, 10].
When you update a model, Simulink® software displays an error message if what you specify does not match the sample times defined by the model.
If Periodic sample time constraint is set
to Unconstrained, Simulink software assigns priority 40 to the model base
sample rate. If Higher priority value indicates higher
task priority is selected, Simulink software assigns priorities 39, 38, 37, and so on,
to subrates of the base rate. Otherwise, it assigns priorities
41, 42, 43, and so on, to the subrates.
Continuous rate is assigned a higher priority than is the
discrete base rate regardless of whether Periodic
sample time constraint is
Specified or
Unconstrained.
This parameter is enabled by selecting Specified
from the Periodic sample time constraint
list.
Parameter:
SampleTimeProperty |
| Type: structure |
| Value: any valid matrix |
Default:
[] |
Note
If you specify SampleTimeProperty at the command
line, you must enter the sample time properties as a structure with
the following fields:
SampleTime
Offset
Priority
