control de posicion con puente h

[edcocu]

hola quiero controlar la posicion de un motor DC, utilizo un encoder para medir dicha posicion y una tarjeta usb6008 para controlar dicho motor; pero a la salida de la tarjeta le acodiciono un puente h para no quemar mi tarjeta, este puente h recibe dos pulsos de mi tarjeta para controlar el giro de mi motor ya sea horario o antihorario, he cho una simulacion en simulink y sale bien y obtengo mis ganancias para mi controlador pid, pero solo tengo una salida del controlador q implento en labview, ¿como hago para esta q salida puede posicionar el motor dc controlando el puente h ?; es decir si le doy un set point mi motor debe ser capaz de posicionarse ya sea girando horario o antihorario.

hello i want to control the position of a DC motor, use an encoder to measure the position and a card usb6008 to control this engine, but the card output bridge h acodiciono him not to burn my card, this bridge h receives two pulses my card to control my motor turning either clockwise or counterclockwise, I have cho a simulation in simulink and goes well and I get my winnings to my controller pid, but I have only one controller output in labview implento q, how do I the output q can position the controlling dc motor h bridge? ie if I give my engine a set point must be able to position either by turning clockwise or counterclockwise.

Thanks for the information,but my question is: I want to control the position of a motor dc, this motor can move from 0 to 5 volts and i measured the position with an encoder that gave me angles from 0 to 280 degrees, i want to set my motor in a desired position from 0 to 5v (0 to 280º)  and my dc motor have to stop in the setpint position; but my dc motor have to move in a clockwise or counterclockwise depend if my setpoint is greater than actual angle o viceverse.
