Implements autotuning using the Chien-Hrones-Reswick tuning method.
Formula to use to convert the model to PID parameters.
Name | Value | Description |
---|---|---|
Regulator - 0% | 0 | Uses the regulator formula for 0% overshoot. |
Regulator - 20% | 1 | Uses the regulator formula for 20% overshoot. |
Servo - 0% | 2 | Uses the servo formula for 0% overshoot. |
Servo - 20% | 3 | Uses the servo formula for 20% overshoot. |
Default: Regulator - 0%
Parameters to return as PID gains.
Name | Value | Description |
---|---|---|
P | 0 | Returns only the proportional parameters. |
PI | 1 | Returns the proportional and integral parameters. |
PID | 2 | Returns the proportional, integral, and derivative parameters. |
PD | 3 | Returns the proportional and derivative parameters. |
Default: P
Stimulus signal for the system.
Response signal of the system.
Initial value for the controller gain.
This node uses this input to calculate integral of PID gains.
Default: 0
Loop-cycle time or interval, in seconds, at which this node is called.
dt must be greater than zero.
Default: 0
