Abstract The Preisach model is a well-known of hysteresis in the modern nonlinear science. This paper provides an overview works that are focusing on study dynamical systems from various areas (physics, economics, biology), where plays key role formalization dependencies. Here we describe input-output relations classical operator, its basic properties, methods constructing output using demagnetization function formalism, generalization operator for case vector relations. Various...
The synthesis of MIMO fault-tolerant control systems under failures is considered. solution written in an analytical form, which makes it possible to synthesize simplified circuit implementations and adjust coefficients the system case a non-stationary object. А nonlinear medium-range aircraft model was used verify results.
The task of decentralized coordinated control for vertical trajectory movement a group different types pilotless aircraft is considered here. do not exchange information. Remote each plane realized by ground-based command post with radio channel. An approach to model coordination used compound system local multiple-input multiple-output (MIMO) subsystems. based on the results embedding technology.
The paper proposes a method for implementing universal neural network processor with hysteresis dynamics. This allows wide range of heterogeneous tasks in real time to be performed without reprogramming and changing their internal structure. Adding behavior the system makes it possible increase resistance external influences, complexity as well non-linearity intelligent output. discusses use this part an on-board avionics system.
