Abstract

This paper investigates limit oscillations in an adaptive sampling system whose associated sampling instants are generated from a constant difference of amplitudes. The control law to the linear part is a piecewise - constant control generated from such an adaptive sampling rule. The limit oscillations which are generated are interpreted from the equivalence of the sampling and hold device with a nonlinear one consisting in a multiple relay with hysteresis.
