Servosystems Basic Unit for DC Motors

The Servosystems Basic Unit for DC Motors, is an unit whose goal is studying low power servo systems. It is a low power DC motor speed control trainer that has a breakdown simulator.

ATENG 12380 — Servosystems Basic Unit for DC Motors

• 1 ATENG 12380. Unit:
• Base Unit:
  Steel box.
  Diagram in the front panel with similar distribution to the elements in the
  real unit.
  Electromechanic unit.
  Tachometric adaptor.
  Generation and control of set point.
  Ramp generator, as well as sinusoidal, triangular and square wave generator.
  PWM modulator.
• Unit: ATENG 12380
  Open loop control.
• Close loop control:
  Proportional Control (P).
  Integrative Proportional Control (PI).
  Proportional derivative Control (PD).
  Proportional Integrative derivative control (PID).
  Current limiter.
  Turn inversion control.
  Stop/starting control.
  Power stage and excitation of the power stage.
  Brake control.
  Fault simulator that allows the entries of a considerable amount of dysfunctions in order to the students diagnose its nature and find
  out the components that cause them. Without taking risks to provoke any damage in the unit.
• Type of faults included in the unit:
• Fault 1: The absolute value of the feedback signal from the tachogenerator is not calculated for its subtraction from the
  reference, thus, for one of the turning senses, the error is wrong.
• Fault 2: The value of the Proportional constant of the PID is divided by ten with the user unable to detect it but its effect.
• Fault 3: The value of the Integral constant of the PID is divided by ten with the user unable to detect it but its effect.
• Fault 4: The value of the Derivative constant of the PID is divided by ten with the user unable to detect it but its effect.
• Fault 5: The signal from the tachogenerator is modified, making the PID control to believe that the speed is ten times lower to
  the real one.
  None of these faults are exclusive, being possible to combine them.
  Direct current motor (DC) and tachometric generator.
• 2 SERIN/CCB/CCSOF. Computer Control Software:
  Compatible with actual Windows operating systems. Graphic and intuitive simulation of the process in
  screen. Compatible with the industry standards.
  Registration and visualization of all process variables in an automatic and simultaneously way.
  Flexible open and multicontrol software, developed with actual windows graphic systems, acting
  simultaneously on all process parameters.
  Management, processing, comparison and storage of data.

SERIN/CCB/CCSOF

Comparative analysis of the obtained data, after to the process and modification of the conditions during

the process.
