| Abstract |
A prototype of an automatic micropositioning
system was developed. This prototype uses a shape
memory alloy (SMA) actuator, a dedicated PI controller
and a piece of software to command a desired motion
profile for the actuator. The proposed micropositioning
system is characterized by a 4 mm stroke, a 1 μm
resolution and a 70 g nominal force and can be
commanded directly from a personal computer and
without human retroaction. The closed loop positioning
resolution (1 μm) is obtained in spite of inaccurate system
behaviour during its movement. |
