NTC-09.01 «Elements of automatic control systems»

Br0.00

The training laboratory system is designed to be used as a teaching facility for laboratory and practical experiments in higher, secondary and vocational educational institutions.

Category: Automation, automatic equipment and control systems

Structurally, the unit includes electrical equipment, electronic circuit boards and a front panel. On the front panel there are control elements (buttons, switches, variable resistors), sockets for connecting wires, USB port.

The unit allows to gain basic and deep knowledge in the following spheres:

investigation of automatic control systems;
adjustment of a full-scale PID controller, automatic microprocessor-based control system on the basis of microprocessor TRM PID-controller.

According to the function, the front panel is divided into the following sections:

dynamic links area. In the middle of the section there’s a schematic diagram of a start-up circuit. At the bottom, there are knobs for setting rung coefficient, dual-channel USB oscilloscope connection panel, function generator connection panel.
EP oven emulator area. The emulator is a circuit board in a transparent housing. The board features a 10W heater with a TSM 50M thermistor inside.
TRM area includes the controller itself.

Measurement systems includes dual-channel USB oscilloscope, 10 MHz bandwidth, 100 MB/s access speed (real-time), 2GB/s equivalent-time sampling, 1 MB/s USB stream sampling, memory buffer for 8.000 samples (divided between active channels), digital instrumentation for measuring time and temperature.

The front panel includes special sockets for connecting to measurement inputs of dual-channel USB oscilloscope, which allow to take oscilloscope traces of test points’ signals.

Also, there’s a USB port for PC or laptop connection.

The unit includes interference protection system to ensure clear measurement results of microprocessor sensors.

Before conducting experiment on the hardware students make computer models of the investigated objects. All the models created in Scilab computation system are included among the methodical guidelines.

The training system is supplied with:

a set of teaching materials and technical documentation intended for the teaching staff;
a software.

Experiments provided

Determination of transitive functions of typical dynamic links of automatic control systems, characterization of frequency and phase properties.
Besides experimental investigations students test computer models of typical dynamic links, analyze transitive, frequency and phase properties as well.
Determination of contact ration and transitive function of the elements of automatic control system: controlled object, amplifier, feedback.
At first, students perform the investigation on a computer model of PID-controller, than repeat it on the real hardware.
Stability of linear ACS with a proportional action controller.
Before the experiment students create computer models of looped control systems:
– with inertial OA link;
– with oscillatory OA link.
Models allow to generate frequency plots (Nyquist, Bode, frequency responce) and observe transitive processes.
Determination of ACS quality.
According to the characterization from the previous experiment quality properties of ACS are analyzed, as well as ACS with inertial link using integral estimate.
Investigation of ACS with a full-scale PID-controller.
The experiment includes adjustment of a virtual ACS PID-controller, build in Scilab and a full-scale industrial PID-controller of the training unit.
