Preisach Model Identification of a Two-Wire SMA Actuator

چکیده
In recent years, the Preisach hysteresis model has emerged as the model of choice for the behaviour of many smart materials, such as shape memory alloys (SMA). This research treats the identiication of Preisach models for a diierential SMA actuator. The traditional identiication technique is applied, and several models are derived for the actuator. It is seen that the classical Preisach model is able to model its behaviour. However, the results raise questions concerning the robustness of the traditional identiication technique, as well as the conservative nature of current passivity-based control results for the Preisach model.

متن کاملHysteresis Modeling, Identification and Fuzzy PID Control of SMA Wire Actuators Using Generalized Prandtl-Ishlinskii Model with Experimental Validation
In this paper, hysteretic behavior modeling, system identification and control of a mechanism that is actuated by shape memory alloy (SMA) wires are presented. The mechanism consists of two airfoil plates and the rotation angle between these plates can be changed by SMA wire actuators. This mechanism is used to identify the unknown parameters of a hysteresis model. Prandtl–Ishlinskii method is ...
متن کاملA Novel Preisach Based Neural Network Approach to Hysteresis Non-Linearity Modeling
In some systems with hysteresis behavior like Shape Memory Alloy (SMA) actuators and Piezo actuators, we essentially need an accurate modeling of hysteresis either for controller design or performance evaluation. One of the most interesting Hysteresis non-linearity identification methods is Preisach model in which hysteresis is modeled by linear combination of elemental operators. Despite good ...
متن کاملHysteresis Nonlinearity Identification Using New Preisach Model-Based Artificial Neural Network Approach
Preisach model is a well-known hysteresis identification method in which the hysteresis is modeled by linear combination of hysteresis operators. Although Preisach model describes the main features of system with hysteresis behavior, due to its rigorous numerical nature, it is not convenient to use in real-time control applications. Here a novel neural network approach based on the Preisach mod...
متن کاملNonlinear Analysis of a Flexible Beam Actuated by a Couple of Active SMA Wire Actuators
There are two different ways of using SMA wires as actuators for shape control of flexible structures; which can be either embedded within the composite laminate or externally attached to the structure. Since the actuator can be placed at different offset distances from the beam, external actuators produce more bending moment and, consequently, considerable shape changes with the same magnitude...
