automatic voltage regulator using labview

[marvel89]

i want to develop  a computer controlled Automatic Voltage Regulator to control the output voltage of a 440v, 3Φ ac generator. {i am using only single phase of the generator }

i am  stepping down the output voltage of the generator below the ratio of DAQ card i.e. 10v using a step down transformer{230 v to 6 volts } .Using this voltage as an input to a close loop Lab VIEW program we are controlling an external Relay Circuit .The Relay Circuit controls a bank of resistors to vary the excitation voltage. The Lab VIEW program broadly has a filter block, a comparator block and a digital output block, but i am unable to control the output voltage , can you plz suggest any changes to program or any thing wrong in it

Please re-post your request in the appropriate LabVIEW forum, this one here is dedicated to CVI, which is a different software platform
