Block that outputs satisfied = false
if
abs(u1-u2) > threShold
within the prescribed time intervals,
or satisfied = true
otherwise.
Implementation
The test uses a hysteresis of plus/minus 1% in order to avoid
chattering if abs(u1-u2)
is near threShold
.
The difference abs(u1-u2)
is filtered with a first order filter with time constant tau
.
This guards against rounding errors in event handling by upstream signal-generating blocks.

Reformulated model to allow scheduling of time events as opposed to state events,
