The Industrial Emulator / Servo Trainer is ideal for studying control of practical systems in both the educational and industrial work places. A variety of features support the introduction and removal of non-ideal properties that are prevalent in real-world industrial applications. The mechanism provides for the easy adjustment of:

  • Drive and load inertias
  • Gear ratio
  • Disturbance torques (programmable)
  • Viscous or Coulomb Friction
  • Backlash
  • Drive Flexibility

This system is furnished with a comprehensive set of experiments that provide an excellent introduction to applied control system fundamentals. It includes a special section on practical control implementation where the above non-ideal properties are studied and their effects mitigated through feedback control. Further experiments address practical issues such as sensor quantization, sample period, and drive saturation.
