blockIntegrator
Output the integral of the input signal (continuous or discrete block)
Extends from Modelica_LinearSystems2.Controller.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) |
| Boolean | limitsAtInit | true | = false, if limits are ignored during initializiation (i.e., y=u) |
