Abstract
The present paper describes research results considering the automatic control of a prehension module using a dual shape memory alloy (SMA) actuator. The offspring targeted a high-speed prehension appliance by means of adjusting constants of a PID controller. Furthermore, SMA springs are individually driven according each one’s particularities, aiming at prolonging life of dual SMA actuator, with respect to parametric values given by manufacturer. Problem of process control is approached from few perspectives: automatic control, software implementation and electronic performance, the first being the one subjected to following discussion.

Improving Filter Performances for Conducted Electromagnetic Interferences Suppression
Improving the performances of a filter for conductive electromagnetic interferences suppression involves two major directions of action: the first direction refers to the increase of attenuation at high frequency, while...
Critical Buckling Force Variation for Beams with Discontinuities
This paper introduces a method to evaluate the critical buckling force for beams with geometrical discontinuities. First the shape of the healthy deformed beam due to axial forces is analyzed, in order to predict the dis...
