Muscular hydraulics drive larva-polyp morphogenesis

open access: yesCurrent Biology, 2022
Development is a highly dynamic process in which organisms often experience changes in both form and behavior, which are typically coupled to each other. However, little is known about how organismal-scale behaviors such as body contractility and motility impact morphogenesis.

Modeling and Identification of the Hydraulic Servo Drive [PDF]

open access: yesEPJ Web of Conferences, 2019
This paper discusses possibilities to apply the dynamic identification with a discrete linear model while assessing the state of the electro-hydraulic drive dynamics. This evaluation is crucial while designing modern power or positional control systems.

Nonlinear Control of Hydraulic Drives

open access: yesIFAC 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 ...
