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 ...
