Linear Second-Order Actuator
A second-order linear model of the actuator.
Description
The Linear Second-Order Actuator block realises the drive model as a second-order transfer function
where
-
- is the natural frequency of the drive, rad/s;
-
- is the damping coefficient of the drive.
|
In domestic sources it is customary to write down the transfer function of the second order in the form of where is the time constant of the drive, s. The natural frequency of the drive is the inverse of the drive time constant: . |
Parameters
Natural frequency - natural frequency of the drive
1.0 (by default) | scalar
Natural frequency of the drive, rad/s.
Data types: Float64.
Damping ratio - drive damping ratio
0.3 (by default) | scalar
Drive damping ratio.
Data types: Float64.
Initial position - initial position of the actuator
0.0 (by default) | scalar
Initial position of the actuator. The units of the initial position and the required actuator position must match.
-
Data types:
Float64.
Initial velocity - initial velocity of the drive
0.0 (By default) | scalar
Initial velocity of the drive.
Data types: Float64.
