Abstract
In this paper, a quantized adaptive decentralized output feedback control is proposed for a
class of interconnected nonlinear systems with quantized input and possible number of hysteretic actuators
failure up to in nity. The hysteretic actuators nonlinearities are described by the Prandtl-Ishlinskii model.
In order to compensate the effects of the possible number of the hysteretic actuators failures up to in nity
and input quantization, a modi ed backstepping approach is proposed by utilizing the high-gain k- lters,
hyperbolic tangent function property, and bound estimation approach. It is proved both mathematically and
by numerical simulations that using the proposed controller, all the signals of the closed-loop system are
globally bounded despite of the input quantization and possible number of hysteretic actuators failures up to
in nity.
