Ideal Integrator (no Delay)

Models an ideal discrete integrator without delay considering op-amp saturation.

Library

SD Toolbox.

Description

The Ideal Integrator (no Delay) block models a real discrete integrator without delay considering op-amp saturation.

The implemented transfer function in the z-domain is

The saturation levels of the operational amplifier are modeled using a saturation block inside the feedback loop of the integrator.

Parameters

Sample Time: Period of the sampling signal in s (T_s = 1/f_s, where f_s is the sampling frequency)
Saturation: Saturation voltage of the op-amp used in the integrator in V
