The device that causes the process to provide the
output. The device that provides the motive power to the
process. |
|
Unidirectional,operational blocks that represent the
transfer functions of the elements of the system. |
|
The relation formed by equating to zero the
denominator of a transfer function. |
|
The case where damping is on the boundary between
underdamped and overdamped. |
|
An oscillation in which the amplitude decreases with
time. |
|
A measure of damping. A dimensionless number for the
second-order characteristic equation. |
|
An electric actuator that uses an input voltage as a
control variable. |
|
A transformation of a function f (t )from the time
domain into the complex frequency domain yielding F (s ). |
|
An approximate model that results in a linear
relationship between the output and the input of the device. |
|
A system that satisfies the properties of
superposition and homogeneity. |
|
A rule that enables the user to obtain a transfer
function by tracing paths and loops within a system. |
|
Descriptions of the behavior of a system using
mathematics. |
|
A diagram that consists of nodes connected by several
directed branches and that is a graphical representation of a set of
linear relations. |
|
A model of a system that is used to investigate the
behavior of a system by utilizing actual input signals. |
|
The ratio of the Laplace transform of the output
variable to the Laplace transform of the input
variable. |
