Model-based precision position and force control of SMA actuators with a clamping application

Autor: Arathi Pai, Ansgar Trächtler, Markus Riepold

Publikováno v: Mechatronics. 50:303-320

This paper presents a novel control strategy for precision control of Shape Memory Alloy (SMA) actuators by using a combination of large and small-signal controllers. The large-signal controller, responsible for coarse positioning, is a nonlinear PID

Real-Time Compatible Phenomenological Modelling of the Austenitic Phase in Shape Memory Alloys as an Example for Modelling of Materials with Repeatable Non-Linear Characteristics

Autor: Ansgar Traechtler, Arathi Pai, Mirko Schaper

Publikováno v: IFAC-PapersOnLine. 48:1043-1048

Shape Memory Alloys (SMAs) are attractive materials for a variety of applications due to advantages such as high reversible strains, high specific actuation stresses and high energy density. The extreme non-linearity inherent in SMAs, however, makes
