Motion sensor in mechanical translational systems
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 = vR – vC, where vR,vC are the absolute velocities at ports R and C, respectively.
The block has the following ports:
