Abstract :
A servosystem containing a relay with dead zone and hysteresis is considered. A new frequency-domain stability criterion is given by taking into account the particular characteristics of the nonlinearity, and it is shown that if the linear subsystem in the feedback loop contains a free integrator and its frequency response satisfies this criterion, then the error settles within the dead zone after a finite time.
