This blocks defines the transfer function between the input u and the output y as integrator:
1
y = k * (1 + ------ ) * u
T*s
T*s + 1
= k * --------- * u
T*s
The block can be continuous or discrete (with continuous parameterization).
It is not possible to initalize a continuous integrator in steady state. For this reason, option "initType = SteadyState" is ignored for a continuous PI block and interpreted as "initType = InitialState".
