Converts PID gains in the Academic, Parallel, or Series form to the normalized Parallel form that the PID VI expects.
Use the following table to understand the details about the equations that the Convert PID Gains VI uses when converting the PID gains. The converted PID gains are Kp, Ki, and Kd, respectively.
| Original PID Form | Original Gains: Units | Conversion Equations |
|---|---|---|
| Academic | Kc: Gain (K) |
|
| Ti: s | ||
| Td: s | ||
| Parallel | Kp': Gain (K) |
|
| Ki': Hz | ||
| Kd': s | ||
| Series | KC': Gain (K) |
|
| TI': s | ||
| TD': s |
