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)




Description:

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.

Transfer function (zero-order hold discretization method):

              1
G (z) = KiTs------
            z - 1
