UNTRADITIONAL ACTUATORS SMA TYPE -MODELING OF HYSTERESIS

UNTRADITIONAL ACTUATORS SMA TYPE -MODELING OF HYSTERESIS

Paper in proceedings (conference paper)

The shape memory materials are known since first half of the twentieth century. The example of these materials could be a Shape Memory Alloys (SMA). Because of their attributes, the engineers usually call them a „smart materials“. The SMA can be used in many static or dy-namic applications for example in problem of actuators. Thanks to the SMA materials sophis-tication and associated shape memory effect, there are some issues (hysteresis, degradation etc.), which can complicate their prospective usage. The attributes of SMA classified these actuators to the category of non-linear system with hysteresis. This article deals with the SMA use and potential hysteresis modeling approaches. Several model examples are discussed.
