Linear Second-Order Actuator

Implement second-order linear actuator

Library

Actuators

Description

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

Dialog Box

Natural frequency

The natural frequency of the actuator. The units of natural frequency are radians per second.

Damping ratio

The damping ratio of the actuator. A dimensionless parameter.

Initial position

The initial position of the actuator. The units of initial position must be the same as the units of demanded actuator position.

Initial velocity

The initial velocity of the actuator. The units of initial velocity must be the same as the units of demanded actuator velocity per second.

Inputs and Outputs

InputDimension TypeDescription

First

 Contains the demanded actuator position.

OutputDimension TypeDescription

First

 Contains the actual actuator position.
