Nonlinear Control of Hydraulic Drives
IFAC Proceedings Volumes, 1984 Abstract The application of modern unconventional control theory is described for a hydraulic cylinder. These systems are significantly characterized by noncontinuous non-linearities. A complete model of the hydraulic system is derived. A simplified and partly linearized model underlies two control concepts: The first concept deals with the ...

Hydrogel‐Based 3D‐Printable Stretchable Pressure Sensor
Advanced Materials Technologies, EarlyView.We present a carbon‐black‐functionalized double‐network granular hydrogel (DNGH) pressure sensor capable of detecting pressures from 200 Pa, equivalent to a light finger touch, up to 500 kPa. The sensor exhibits signal drifts below 3.5% after 800 cycles and response times around 80 ms. Leveraging this broad sensing range, we 3D print this material into
