Preparative Regulation control allows objective show of PID regulator in practises. It´s intended for practical verification of theoretic knowledge get from education of measuring and operative technics. With the aid of this preparative student can simply master the principles of regulators and importance of their PID parametres. Setting of parametres is possible to implement in continuous or discrete area.
Preparative Regulation control is composed of main control unit and simple preparatives illustrating set tasks. Standardly two illustrating tasks are delivered. These two tasks is possible to replenish with your own tasks based on defined interface. Preparative is controlled by rendering application through USB bus and also it can be diagnosed through CAN bus. Under system Windows application allows objective graph viewing, setting parametres of regulation, definition of new tasks and export of acquired data into Excel format.
| Parameter | Measure |
| Supply voltage | 7 to 25V |
| Working temperature | -25 to 60°C |
| 4x analogue input (AI0- AI4) | 0 to 5V |
| 1x pulse input (Pulse 0) | |
| 2x PWM input (PWM0, PWM1) | 0-100%, 1 kHz |
| 1x CAN 2.0A | 250 kb/s |
| 1x USB 2.0 | 2 Mbit/s |
Control unit is based on microprocessor with integrated USB and CAN bus. Processor contains program implementing PID regulation. Unit is inserted into relevant module. By this connection come up illustrating task.
For supply of control unit connected with adjunct unit serves 12V source.
Card values:
PRI: 230V, 50Hz, 48W
SEC: 12V, 2000mA, 24VA
USB cable connect control unit with personal computer equipped with at least one USB port.
It´s impossible to imagine automatization and industry without movement. Bulk of the driving gears is created by larger or smaller engines and small motors with necessitated regulation of revolutions. And this preparative is focused just to this problem.
In task are used two little motors with permanent magnets. First of them creates motive power, second creates braking power. Regulation is executed by inserting specified tension of exciting coil by PWM.
Admeasurement of revolutions is retroactively scanned by aid of pulsed sensor. Get signal is worked up and evaluated by control unit.
Preparative serves as illustrating task of temperature regulation. Source of warmth is lightbulb. Ventilator with surroundings effects as cooling failure.
Temperature is scanned by integrated sensor SMT160-30, which generate signal in form of pulse ratio. This type of signal is very suitable for analogue even digital admeasurement.
DC = 0.32 + 0.0047 x t
Where "t" is temperature in centigrade degrees and "DC" is pulse ratio of output signal in frequence 1 - 4 kHz.
Interface between user and control unit is created by service software working under Windows system. Application Regulation control was designed with regard for easiness of handling and usage of maximum influence while education. Main window of application contains quantity of components for desired regulation parameters setting in right part.
Activation of preparative
In nowadays quickly evolving industry we get in touch more and more often with CAN bus. Because of it preparative Regulation control is equip with this interface. Thus students have possibility to extend their knowledge of modern communication bus. To this purpose is neccesary to buy USB-CAN converter, which is intended mainly for simple dynamic debugging of CAN applications and for prompt and well-aranged diagnostics of CAN unit.
Control unit transmits periodically to CAN unit information about requested value, real value, control deviation, action interference and failure. With aid of converter we can also change value of requested value and size of failure.
For this converter we offer discount 15% to schools.
Maybe the best method of education is learning from personal errors. However errors created on working places of assorted types by bad choice of PID parametres cost too much! Whether it´s concerned about quantity of absorbed energy, or interception of operating because of breach of technical conditions for production.
With preparative Regulation Control scholars and students can try and assume basic ability of so complicated dilemma as regulation surely is. In lessons of measuring and regulating technics they can check out single types of regulators with settings of their parameters and they doesn´t need to be afraid of unfortunate consequences after wrong chosen type of regulator or regulation parameter.
