Motion Sensor

Measure motion of driveline axis

Library

Sensors & Actuators

Description

The Motion Sensor block senses the motion of a driveline axis. The block can output the motions as a set of three Simulink® signals for the angle (p), angular velocity (ω), and angular acceleration (α), in radians, radians/second, and radians/second2, respectively. You can select any combination or all of these output signals. The motion measured is absolute.

The Motion Sensor block has one driveline port. You can connect it to a driveline axis

  • By connecting the port to the end of the axis

  • By branching a connection line off the main line and connecting it to the port

Dialog Box and Parameters

Show angular position port (p)

Select this check box to create a Simulink outport on the block for the angular motion signal. This signal has units of radians (rad). The default is unselected.

Initial angle

This field is active only if the Show angular position port check box is selected. Enter a value for the initial angle of the axis motion, in radians (rad). The default is 0.

The measured angle is this value plus the time integral of the angular velocity, from the start time to the current simulation time.

Show angular velocity port (v)

Select this check box to create a Simulink outport on the block for the angular velocity signal. This signal has units of radians/second (rad/s). The default is selected.

Show angular acceleration port (a)

Select this check box to create a Simulink outport on the block for the angular acceleration signal. This signal has units of radians/second2 (rad/s2). The default is unselected.
