blockIntegratorWithReset

Output the integral of the input signal

Extends from Modelica.Blocks.Interfaces.SISO (Single Input Single Output continuous control block).

Information

This model is similar to Modelica.Blocks.Continuous.Integrator except that it optionally allows to reset the output y of the integrator.

The output of the integrator can be reset as follows:

If reset = TRANSFORM.Types.Reset.Disabled, which is the default, then the integrator is never reset.
If reset = TRANSFORM.Types.Reset.Parameter, then a boolean input signal trigger is enabled. Whenever the value of this input changes from false to true, the integrator is reset by setting y to the value of the parameter y_reset.
If reset = TRANSFORM.Types.Reset.Input, then a boolean input signal trigger is enabled. Whenever the value of this input changes from false to true, the integrator is reset by setting y to the value of the input signal y_reset_in.

To adjust the icon layer, the code of Modelica.Blocks.Continuous.Integrator has been copied into this model rather than extended.

Type	Name	Default	Description
Real	k	1	Integrator gain
TRANSFORM.Types.Reset	reset	TRANSFORM.Types.Reset.Disabled	Type of integrator reset
Initialization
Modelica.Blocks.Types.Init	initType	Modelica.Blocks.Types.Init.InitialState	Type of initialization (1: no init, 2: steady state, 3,4: initial output)
Real	y_start	0	Initial or guess value of output (= state)
Integrator reset
Real	y_reset	0	Value to which integrator is reset, used if reset = TRANSFORM.Types.Reset.Parameter

Type	Name	Description
RealInput	u (from SISO)	Connector of Real input signal
RealOutput	y (from SISO)	Connector of Real output signal
Modelica.Blocks.Interfaces.RealInput	y_reset_in	Input signal for state to which integrator is reset, enabled if reset = TRANSFORM.Types.Reset.Input
Modelica.Blocks.Interfaces.BooleanInput	trigger	Resets the integrator output when trigger becomes true
