Nonlinear Model and Control of Electro Hydraulic Servo-Systems
, 2018 In many applications, the use of hydraulic drives is still preferable to other driving powers. For instance, in shaking table systems for simulating earthquake signal, hydraulic actuators are still widely applied, because the technology of electrical actuators does not(yet) provide the superior performance of hydraulic actuators in generating high ...
