MODAL ANALYSIS OF LINEAR ACTUATOR
Issues of radio electronics, 2018The question of checking the linear drive for resistance to resonance in the structure of the precision positioning mechanism for space applications - hexapod, when it is taken to a near-earth orbit is considered. Calculation of the values of the natural frequencies of the structure is carried out by the finite element method using CAD. The application

The unique properties of SMA microactuators appear to be very attractive for microrobotic applications. In the following, SMA linear actuators and related optical microswitches and microgrippers will be discussed. As for SMA microvalves, a dedicated technological approach is pursued for their realization, which is based on micromachining SMA plates or ...

Global Control of Linear Systems with Saturating Actuators
Automatica, 1998Continuous-time linear systems with saturating actuators are considered. A gain-scheduling controller is introduced where the actuator characteristic is accounted for in the design of the controller. Several control problems, e.g. global asymptotic stabilization, disturbance rejection, robust stabilization, etc. are treated in this paper.

A novel ultrasonic linear actuator
[Proceedings] 1990 IEEE 7th International Symposium on Applications of Ferroelectrics, 2002An ultrasonic linear actuator operated by a combined wave of longitudinal vibration and flexural vibration excited by nonlinearly connected bars is described. A multilayered piezoelectric actuator was used at the actuator, and aluminum bars as the elastic body.
