“…Phenomenological models, on the other hand, are used to produce behaviors similar to those of physical systems without necessarily providing physical insight into the problems. A popular phenomenological hysteresis model adopted for smart materials is the Preisach model (Adly, Mayergoyz & Bergqvis, 1991;Hughes & Wen, 1994;Ge & Jouaneh, 1996;Gorbet, Wang, & Morris, 1998;Cruz-Hernandez & Hayward, 2001;Tan, Venkataraman, & Krishnaprasad, 2001;Natale, Velardi, & Visone, 2001;Croft, Shed, & Devasia, 2001), where the hysteresis is modeled as a (weighted) aggregate e ect of all possible delayed relay elements. A similar operator using delayed relays of ÿnite slopes, called Krasnosel'skii -Pokrovskii (KP) operator, has also been used ( Banks, Kurdila, & Webb, 1997;Galinaitis & Rogers, 1998).…”

A novel dynamic model is proposed for the hysteresis in magnetostrictive actuators by coupling a Preisach operator to an ordinary di erential equation, and a parameter identiÿcation method is described. An e cient inversion algorithm for a class of Preisach operators with piecewise uniform density functions is then introduced, based upon which an inverse control scheme for the dynamic hysteresis model is presented. Finally the inversion error is quantiÿed and l1 control theory is applied to improve the robustness of inverse compensation. Simulation and experimental results based on a Terfenol-D actuator are provided. ?

“…Unfortunately, they require huge efforts in identification procedures and high computational weight, so resulting unsuitable for sensing or actuation tasks. As a consequence, other approaches have been considered with the aim to gather good generality and modeling capabilities to a relative simple handling and computational effort, [28], [1], [42]. There, the basic concern was to fully exploit the "machinery" of the classical hysteresis operators, well suited to link together one input to one output.…”

“…Phenomenological models, on the other hand, are used to mimic the behaviors of the physical systems without necessarily providing physical insight into the problems. A well-known phenomenological hysteresis model for ferromagnetic as well as smart materials is the Preisach model, Adly et al (1991), Hughes and Wen (1995), Ge and Jouaneh (1996), Gorbet et al (1998), Cruz-Hernández andHayward (2001), Tan et al (2001), Croft et al (2001), where the hysteresis is modeled as a (weighted) aggregate effect of all possible relay elements that are delayed with respect to each others. Particularly, the Preisach model has been adopted as an effective hysteresis model of ER fluids, Han et al (2003), piezoelectric materials, Ge and Jouaneh (1997) and Shape Memory Alloys, Gorbet et al (1998).…”

Recent research intended to integrate robots into the anthropic domains has introduced a new set of challenges with regard to design and control of such robots. Among these challenges, human safety is perhaps one the most predominant issues. While, existing solution relies on highly specialized and high cost actuation mechanisms, a new generation of intrinsically safe robots (manipulators) that use alternative technologies is yet to prevail. There is however a general consensus that the conventional actuation mechanisms are not capable of providing intrinsic safety while maintaining the high performance of the robot. On these premisses, a new Magneto-Rheological (MR) based actuation mechanism was developed in our research group. The actuator uses a magnetic field to precisely control its output torque delivery. The actuator demonstrates remarkable mass to torque ratio and low output inertia, at the same time, its bandwidth is comparable, if not better, than current leading actuators. The output torque of the actuator however, is hysterically related to its input current which makes its control challenging. The objective of the current work is to obtain a precise open-loop model that relates the output torque to the applied input current. The advantages of the obtained model are twofold. While such a model enables accurate control of the actuator, hence the actuated mechanism; in our case a robotic arm, it also eliminates the need for a force/torque sensor for performing high fidelity force/torque control tasks. To validate the accuracy of the constructed model simulation results for the output torques are presented and compared to those measured experimentally using the prototyped actuation mechanism. Results agreements attest to the validity of the presented model.
