Relay question

Hello,

I am running into a problem as I am developing a model in Simulink/MATLAB.

Is their an efficient way of doing a multi-level relay? What I mean by that is a curve that has multiple relay/hysteresis loops.

You can think of it as a relay with 3 states, not just on and off.

Also, is there anyway to set a relay block so it defaults to on if the input starts between on and off?

Magneto-rheological damper model that generates the relay loop w.r.t. damping parameters.
