In | Control error input |
Init | Value which is loaded at initialization function call |
Enable | Enable == 0: Deactivation of block; Out set to 0 Enable 0->1: Preload of integral part Enable == 1: Activation of block |

Out | Control value |
Mask Parameters | ||
Name | ID | Description |
Kp | 1 | Proportional Factor |
Ki | 2 | Integral Factor |
ts_fact | 3 | Multiplication factor of base sampling time (in integer format) |
PI controller:
G(s) = Kp + Ki/s
Each fixed point implementation uses the next higher integer data type for the integral value storage variable.
A rising flank at the Enable inport will preload the integral part with the value present on
the Init inport.
Transfer function (zero-order hold discretization method):
Developer note: The source code of block PILimit is used.
