How to fill it
Fill the inputs. The tool shows the outputs.
On the tool screen, Calc is the working sheet. Presets stores values you reuse. Reference is the formula, assumptions, and provenance below.
Formula
overshoot = max(0, max(PV) − SP)Inputs
| Name | Unit |
|---|---|
| Setpoint | 1 |
| PV sample 1 | 1 |
| PV sample 2 (optional) | 1 |
| PV sample 3 (optional) | 1 |
| PV sample 4 (optional) | 1 |
| PV sample 5 (optional) | 1 |
| PV sample 6 (optional) | 1 |
| PV sample 7 (optional) | 1 |
| PV sample 8 (optional) | 1 |
Outputs
| Name | Unit |
|---|---|
| Peak deviation (hero result) | 1 |
| Overshoot | 1 |
| Undershoot | 1 |
| Steady-state error (last sample) | 1 |
Diagnose
This tool does not attach diagnose observations.
Assumptions
- Overshoot is above SP; undershoot is below SP. Last entered sample is treated as the settled value.
Provenance
- Leave unused samples blank. Rise and settling time need timestamps and are not invented here.
