P
Returns proportional gains of a P controller.
Inputs/Outputs
proportional unit
Unit associated with the proportional gain.
The relationship between the available units is K = 100/PB.
This input accepts a ring or an array of rings.
| Gain (K) | 0 | Specifies that the proportional gain is expressed in terms of proportional gain (K). |
| Band (PB) | 1 | Specifies that the proportional gain is expressed in terms of proportional band (PB). |
Default value: Gain (K)
proportional
Value of the proportional component of the controller.
This input accepts a double-precision, floating-point number or an array of double-precision, floating-point numbers.
action
Action of the controller.
This input accepts a ring or an array of rings.
| Reverse | 0 | The controller is reverse-acting. |
| Direct | 1 | The controller is direct-acting. |
Default value: Reverse
proportional gain
Proportional gain of the controller.
This output can return a double-precision, floating-point number or an array of double-precision, floating-point numbers.
Algorithm Definition
The following transfer function represents a P controller:
where Kp is the proportional gain.
