2.- Investigue que otros bloques de aplicacion (objetos) tiene BORIS de WINFACT 96Release 7 of our Windows Fuzzy And Control Tools WinFACT is now available. The main new features are:

Block-oriented simulation BORIS:

A new toolbar (options toolbar) now enables the direct search for blocks or texts as well as the changing of the block sizes without invoking a special dialog. If necessary this toolbar can, of course, be hidden.

The new option Search Text allows you to find concrete parts of structures by descriptive texts very fast (alternatively via dialog or the new options toolbar).

The option to insert scalable bitmaps in system structures makes an even better presentation of the system possible in many cases.

The new option Minimize to toolbar/Restore allows the "folding" of BORIS to toolbar height so that the system structure is no longer visible. Clicking it again restores the original window size.

BORIS now allows the direct determination of the frequency response of a series connection of standard elements (PT1, PT2,...) like it is found e. g. in an open loop. The frequency response can be presented as Bode diagram or Nyquist plot. Furthermore the corresponding transfer function can be shown. Besides a measuring function the display window offers many addional options. The open loop as well as the corresponding closed loop can be displayed.

Besides the known presentation of the whole system structure the improved structure overview enables a relative-to-worksheet, zoomable view with hinttexts. Thus the navigation especially of complex structures has become much easier. Both views allow the direct jump to any position by a double click within the overview window.

Superblock export parameters can now be read from files. Thus especially the parameterization of complex systems with frequent changes of system parameters becomes much easier and the possibility of errors is reduced because it is no longer necessary to open the BORIS system file for changing parameters.

All signal levels can now be marked by color offline and, of course, also during simulation. This new feature especially enables a much better analysis of digital systems.

The new block Logic Analyzer is a display instrument with numerous functions and predestined for the analysis of digital systems.

The new system block MIMO state space model enables the easy simulation of multi-input-multi-output state space systems.

The new multi-time response allows the simultaneous display of up to 50 input signals. Besides a measuring function it offers a lot of further functions.

The new 3D-plotter allows the presentation of system trajectories in the x-y-z-domain and offers numerous options.

By the new block type Block List it is (like it is in the modules LISA and RESY now) possible to build a series connection with standard control elements (PT1, PT2,...) which is then presented within BORIS as one block. The block list can be protected by a password to prevent an unauthorized viewing or changing of the list.

The new block types AUDIOIN and AUDIOOUT now support the sound card of the PCs and allow the input of audio signals and the output via the loudspeakers.

A new visualization block (block type HISTO) allows the calculation and graphical presentation of frequency distributions (histograms).

The new system block TABLE allows the clear presentation of measurement and simulation values in table form with numerous options.

The simulation of control loops with switching controllers has become much easier because of many new switching controllers (most of them with feedback). They all can be found - together with other types of controllers - on the system block palette Controller.

New elements for visualization: horizontal and vertical LED-displays with numerous options (VLEDBAR and HLEDBAR)

The new email client block enables the automatic sending of an email at a defined system state. Besides the message text itself an attachment (e. g. a log-file) can be sent.

The new block type VIEWDOC allows to display any documents (e. g. PDF-files) via mouse click.

Besides the known action and display elements with a separate window for control and visualization now so called in-block-action- and in-block-visualization windows are available. They do not have separate windows so that

the complete system structure is visible during simulation. The interaction with the user resp. the display is realized within the block (therefore the name) itself.

Various new virtual instruments (e. g. I/O-elements with 1-50 in- resp. outputs, function generator) enable an even more comfortable input resp. visualization of simulation and measurement results.

Further new system block types resp. new block features:

Resettable integrator with y0-input

Block type BUTTON now offers the modes switch/button resp. change-over-switch/ change-over-button

Two-point characteristic element with hysteresis

Random generator for various distributions

Four channel oscilloscope

Digital decoder and digital encoder

A/D- and D/A-converter

Frequency counter

Incremental encoder

SIMRESTART-block (allows to restart the simulation using another file)

SIMCANCEL-block with the new operation mode "Terminate simulation and quit program"

All types of controllers can additionally now be found on an extra palette of the system block toolbar. Most controllers can alternatively now be presented resp. operate conform-to-standards, i. e. instead of the error signal the reference and actual value are fed. The error signal is then determined within the controller itself.

BORIS now supports the mouse wheel so that scrolling in complex systems has become much more comfortable.

The improvement of the real time behaviour reduces the deviation between preset and actual simulation step sizes resp. sampling time.

The new autostart function enables the automatic loading and, if desired, starting of the system file that was used last.

Because of the new IDispatch interface BORIS can now work as a COM-automation-server. This enables the "remote control" of BORIS by other applications (e. g. a visual basic program, see screenshot).

3.- Con los datos obtenidos en el desarrollo, grafique en el matlab, la respuesta del sistema generador – motor

4.- Mediante métodos gráficos (constantes de tiempo y constantes de amplitud), y con las graficas obtenidas mediante la tarjeta de adquisision de datos DAQ PCL 821 PG, la tarjeta de conexión (I/O) PCLD-780 de Advantech y el software WINFACT 96; halle el modelo matemático aproximado

2.5 CONCLUSIONES - Para el presente laboratorio se tomaron en cuenta varios aspectos referidos al arranque simple de

un motor de CC para hallar la función de transferencia y un error mínimo- Se vieron distintos tipos de respuesta para hallar el adecuado en este caso es del tercer orden pero

resulta muy conflictivo realizar el análisis del mismo, entonces para realizar cálculos más rápidos pero sin dejar atrás el error mínimo se toma en cuenta el de segundo grado y así tener un aproximado

- Es necesario tener en cuenta los factores que afectan a la realización del presente trabajo como ser no tener en cuenta el reset para eliminar los distintos tipos de datos guardados anteriormente, después ver que el motor tenga una respuesta rápida al pulso dado en un principio , tener en cuenta las demás conexiones

- Tener buen manejo del programa WINFACT además de los demás toolboox q contiene dicho programa
