(for main items)

• With this unit there are several options and possibilities:
• Main items: 1, 2, 3, 4 and 5.
• Optional items: 6, 7 y 8.
• Let us describe first the main items (1 to 5):
• 1 ATENG 12628. Unit:
• Unit:
  Metallic box.
  Diagram in the front panel with distribution of the
  elements similar to the real one.
• Reference signals unit:
  This unit allows to generate four different types
• of signals: step, square, ramp and sine. The
  frequency and amplitude of the signals can be
  adjusted through the computer.
  Step output. Square output. Ramp output.
  Sine output.
• Step: amplitude: 0 V to 5 V, frequency: 0Hz
  to 200 Hz.
• Square: amplitude: ±10 V, frequency: 0Hz to
  200 Hz.
• Ramp: amplitude: ±10 V, frequency: 0Hz to
• Unit: ATENG 12628
  200 Hz.
• Sine: amplitude: ±10 V, frequency: 0Hz to 200 Hz.
• Frequency sweep: this unit performs a frequency sweep needed for calculating the Bode plot.
• PID controller unit:
  This unit is subdivided into proportional, integrative and derivative blocks. The unit allows to adjust
• each parameter independently from the computer:
• P controller: Kc: -10 to +10. I controller: Ti: 0 to 100 s. D controller: Td: 0 to 100 s.
• Sample time: 0.1 to 100 ms.
• Lead/Lag compensator:
  This unit represents a compensator system in the Laplace domain. The system allows to modify the
• zero, the pole and the gain of the compensator through the computer:
• K lead: 1 to 100 s. K lag: 1 to 100 s. Gain: 1 to 10. Sample time: 0.1 to 100 ms.
• Integrator system:
  This unit represents a integrator system in the Laplace domain. The system allows to modify the
• gain and the saturation value of the system through the computer:
• Gain: -10 to 10.
• Saturation: -10 to 10.
• First order system:
  This unit represents a first order system in the Laplace domain. The system allows to modify the time
• constant of the system through the computer. The gain can be also adjusted using the computer:
• Gain: 0 to 10. Time constant T: 0 to 100 s.
• Second order system:
  This unit represents a second order system in Laplace domain. The system allows to modify through
• the computer the three parameters of the system: gain, damping coefficient and the natural
• frequency:
• Gain: 1 to 10.
• Damping coefficient x: 0 to 1.5 in steps of 0.1.
• Natural frequency (w n): 1Hz to 2 p*100 rad/s (100 Hz).
• Perturbation unit:
  This unit allows to insert disturbances in the systems. The perturbation can be inserted in different
• places of the control loop:
• Perturbation value: -10 to 10.
