Linear Second-Order Actuator block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
Aerospace Blockset / Actuators

Description

The Second Order Linear Actuator block outputs the actual actuator position using the input demanded actuator position and other parameters that define the system.

Ports

Input

A_demand — Demanded actuator position

scalar | array

Demanded actuator position, specified as a scalar or array.

Data Types: double

Output

A_actual — Actual actuator position

scalar | array

Actual actuator position, returned as a scalar or array.

Data Types: double

Parameters

Natural frequency — Natural frequency

1 (default) | scalar

Natural frequency of the actuator, specified as a scalar double, in radians per second.

Programmatic Use

Block Parameter: wn_fin

Type: character vector

Values: scalar | double

Default: '1'

Damping ratio — Damping ratio

0.3 (default) | scalar

Damping ratio of the actuator, specified as a scalar double.

Programmatic Use

Block Parameter: z_fin

Type: character vector

Values: scalar | double

Default: '0.3'

Initial position — Initial position

0 (default) | scalar

Initial position of the actuator, specified as a scalar double. The units of initial position must be the same as the A_demand input.

Programmatic Use

Block Parameter: fin_act_0

Type: character vector

Values: scalar | double

Default: '0'

Initial velocity — Initial velocity

0 (default) | scalar

Initial velocity of the actuator, specified as a scalar double. The units of initial velocity must be the same as the A_demand input.

Programmatic Use

Block Parameter: fin_act_vel

Type: character vector

Values: scalar | double

Default: '0'

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"aerolibactuator/Linear Second-Order Actuator"

Example: add_block("aerolibactuator/Linear Second-Order Actuator","myModel/myBlock",MakeNameUnique="on")
