Motion Control Sensors

Sensors contained within a basic motion control system are one or more feedback sensors such as optical encoders, resolvers or Hall effect devices to return the position or velocity of the actuator to the motion controller in order to close the position or velocity control loops.

  

Usage

Common control functions include:

  • Velocity control.
  • Position (point-to-point) control: There are several methods for computing a motion trajectory. These are often based on the velocity profiles of a move such as a triangular profile, trapezoidal profile, or an S-curve profile.
  • Pressure or Force control.
  • Impedance control: This type of control is suitable for environment interaction and object manipulation, such as in robotics.
  • Electronic gearing (or cam profiling): The position of a slave axis is mathematically linked to the position of a master axis. A good example of this would be in a system where two rotating drums turn at a given ratio to each other. A more advanced case of electronic gearing is electronic camming. With an electronic cam, the slave axis follows a profile that is a function of the master position.
