Dead band

This function block implements a dead band. It is mainly used in control system modeling and simulations. A typical application is the elimination of residual error signals in front of a PI-controller.


Y = X - TB       IF       X > TB

Y = X + TB      IF       -X < -TB

Y <= 0.0          IF       -TB < X < TB


Name I/O Type(s) Function
X I FLOAT Input signal
Y I FLOAT Delayed signal
TB I FLOAT Delay time in [s]
