Inports
| |
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 |
Outports
| |
Out | Control value |
Mask Parameters | |
Ki | Integral Factor |
ts_fact | Multiplication factor of base sampling time (in integer format) |
I controller:
G(s) = Ki/s = 1/(Ti*s)
Each fixed point implementation uses the next higher integer datatype for the integrational value storage variable.
A rising flank at the Enable inport will preload the integrational part with the value present on
the Init inport.
