Ideal Translational Motion Sensor

Motion sensor in mechanical translational systems

Mechanical Sensors

Description

The Ideal Translational Motion Sensor block represents a device that converts an across variable measured between two mechanical translational nodes into a control signal proportional to velocity or position. You can specify the initial position (offset) as a block parameter.

The sensor is ideal since it does not account for inertia, friction, delays, energy consumption, and so on.

Connections R and C are mechanical translational conserving ports that connect the block to the nodes whose motion is being monitored. Connections V and P are physical signal output ports for velocity and position, respectively.

The block positive direction is from port R to port C. This means that the velocity is measured as v = vRvC, where vR,vC are the absolute velocities at ports R and C, respectively.

Parameters

Initial position

Sensor initial position, or offset (m). The default value is 0.

Ports

The block has the following ports:

R

Mechanical translational conserving port associated with the sensor positive probe.

C

Mechanical translational conserving port associated with the sensor negative (reference) probe.

V

Physical signal output port for velocity.

P

Physical signal output port for position.

Introduced in R2007a
