Parameters in LabVIEW-model
These parameters have to be set before converting to a VeriStand-model.
Parameters in VeriStand (as inputs)
These parameters have to be set in the system definition file of VeriStand by setting the initial values of the according inputs.
| Nr. | parameter | value | unit | description | comment |
|---|---|---|---|---|---|
| 1 | Control_Strategy | 0 | - | determines how the boiler is controlled by burner power - 0 by target boiler temperature - 1 | is coupled to the hardware parameter HG40 that describes the configuration |
Parameters in VeriStand (as parameters)
| Nr. | parameter | value | unit | description | comment |
|---|---|---|---|---|---|
| 1 | nominal_power[kW] | 20 | kW | nominal power of boiler | is taken as maximal power for control |
| 2 | HG04_power_perc.max | 1 | - | maximal allowed percentage of nominal power | hardware parameter |
| 3 | HG02_power_perc.min | 0,23 | - | minimal allowed percentage of nominal power | hardware parameter |
| 4 | HG22_TK.max | 90 | °C | max. boiler temperature | hardware parameter, relevant for automatic modulation |
| 5 | HG21_TK.min | 20 | °C | min. boiler temperature | hardware parameter |
| 6 | Voltage_run.max | 10 | V | voltage that equals maximal percentage or max. temperature | for PID controller |
| 7 | Voltage_run.min | 2 | V | voltage that equals minimal percentage or min. temperature | |
| 8 | Voltage_off.min | 0 | V | voltage that turns boiler off | |
| 9 | proportional gain (Kc)(13,1) | 0,3 | - | for power control | |
| 10 | integral time (Ti, min)(13,1) | 0,6 | - | for power control | |
| 11 | derivative time (Td, min)(13,1) | 0,00 | - | for power control |
Parameters of / at the hardware.
These parameters have to be adjusted at the hardware itself. They can be found in the subsections of the hardware section.
