Damping device
an actual damping process that stabilises the drive as the load pressure changes. Damping devices can operate mechano-hydraulically as throttle valves or bypass valves or electro-mechanically as solenoid
Chip
integrated circuit. Depending on the technology used, a chip with a size of a few square millimetres can house thousands or hundreds of thousands of gate functions (logic operators), or even an entire mi
Valve dynamics
dynamics, it was agreed to investigate the valve system with sinusoidal signals. Thus valve dynamics can be described as the valve's response to sinusoidal input signals .
Controller synthesis
analysis is performed of the dynamic of the system. Then a search is conducted to find a controller that can provide this data and an initial specification of the necessary control parameters .
Velocity error
setpoint. For this reason the velocity error is also termed the "following error". The velocity error can be reduced by increasing the velocity amplification .
State equations
i), output variables (y i) and state variables (x i) can be pooled into vectors. In the case of linear, time-variable systems, the state equations can be represented as follows: The system matrix A describes [...] standard equations, by introducing state variables x 1(t)...x n(t) as intermediate variables, this can always be converted into a system of differential equations or 1st order differential equations and
Radial piston pump
from an eccentric thrust ring on the outer diameter, which can be moved along a guided route. The output volume or geometric displacement can be changed continuously by moving the eccentric thrust ring [...] radial piston pump, are arranged in a star shape around and perpendicular to the drive axis. They can be subjected to pressure from the inside or outside by pressure fluid and are, amongst other things
Power input pump
and the flow Q as well as from the efficiency factor η of the pump. Alternatively, the power input can also be calculated from the torque M and the rotational speed n:
Operating life of a filter
Estimated time or time determined on similar systems that a filter element can be used before it must be replaced. The operating life is dependent on the filter selected, the amount of contamination that
Absolute measuring system
zero point. Every point on the measured path is identified by a unique signal. Measuring systems that can be used: code straightedge, angular position encoder, resolver , potentiometer among others
