Sensorless force control for dielectric elastomer transducers

Hoffstadt, Thorben ; Maas, Jürgen (2019-05-01)

Multilayer stack-transducers made of dielectric elastomers generate considerable tensile forces and deformations when they are electrically stimulated. Thus, due to their capacitive behavior, they are for example energy efficient substitutes for conventional electromagnetic drives and enable various further completely new applications. Within this contribution, we present a sensorless force con...

Modellierung und Regelung von dielektrischen Mehrschicht-Elastomerwandlern

Hoffstadt, Thorben (2019)

Electromechanical transducers based on dielectric elastomers (DE) can be operated as actuators, generators and sensors. Compared to classic electromagnetic actuators the intrinsic material properties offer significant advantageous e.g. concerning the energy efficiency and density enabling amongst others miniaturization potentials. Researching intelligent supply and control concepts, for example...

Smart sealing for magnetorheological fluid actuators

Hegger, Christian ; Maas, Jürgen (2019-03)

In automotive and industrial environments, magnetorheological fluid–based applications such as clutches and brakes are gaining continuously more attention. However, one of the serious challenges for their application are drag losses at high shear rates. While viscous losses of the magnetorheological fluid can be eliminated by a magnetorheological fluid movement control based on partially filled...

Self-Sensing Control for Soft-Material Actuators Based on Dielectric Elastomers

Hoffstadt, Thorben ; Maas, Jürgen (2019-12-13)

Due to their energy density and softness that are comparable to human muscles dielectric elastomer (DE) transducers are well-suited for soft-robotic applications. This kind of transducer combines actuator and sensor functionality within one transducer so that no external senors to measure the deformation or to detect collisions are required. Within this contribution we present a novel self-sens...
