blockIntegrator
Output the integral of the input signal (continuous or discrete block)
Extends from Interfaces.PartialSISO2 (Partial Single Input Single Output (continuous or discrete) control block of Controller library).
Information
This blocks defines the transfer function between the input u and the output y as integrator:
k
y = --- * u
s
The block can be continuous or discrete (with continuous parameterization).
It is not possible to initalize a continuous integrator in steady state. For this reason, option "initType = SteadyState" is ignored for a continuous integrator block and interpreted as "initType = InitialState".
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Boolean | continuous (from PartialSampledBlock) | blockType == Types.BlockTypeWithGlobalDefault.Continuous or blockType == Types.BlockTypeWithGlobalDefault.UseSampleClockOption and sampleClock.blockType == Types.BlockType.Continuous | True, if continuous block, otherwise discrete block |
| Types.Init | init (from PartialSampledBlock) | Modelica_LinearSystems2.Controller.Internal.convertToInit(initType, sampleClock.initType) | Type of initialization (no init/steady state/initial state/initial output) |
| Real | k | 1 | Integrator gain |
| Boolean | withDelay | false | True, if the output is delayed by one sample period (only if discrete) |
