Servo de posición y velocidad implementado con cilindro diferencial y controlado en LabVIEW para el banco Rexroth
Se presentan las adecuaciones que se hicieron en el banco Rexroth del laboratorio de servosistemas de potencia fluida, adscrito a la escuela de Ingeniería Mecánica. El banco es de uso académico pero todos los elementos que lo integran son de tipo industrial, en el área de servosistemas los elementos...

Feedforward.
We presented the adjustments that were made in the bank Rexroth of labodratory servo fluid power
attached to the School of Mechanical Engineering. The bank use is academic
however all the elements in it are industrial type
in the area of system servo the elements used are type analog
for this reason
is implemented a control computer-aided using an interface plotted on the Labview software which allows handle variates: proportional and derivative. The card used is the DAQ NI USB -6212 National Instruments to send and receive data to a hydraulic system. For hydraulic system two control schemes were developed: the first is a position servo closed loop using as pre-actuator a proportional valve high dynamic response
the actuator is a differential cylinder which can be subjected to disturbance using another smaller differential cylinder located axially. The feedback sign is produced by LVDT position sensor that reads the actual position of the cylinder and using the controller allow locate it in a exactly value. The second is a speed servo open loop whose pre-actuator is a proportional valve acting on a differential hydraulic cylinder longer than the previous allowing better appreciate the changes of speed. The rate can be controlled by varying the valve opening
this is done by sending a step or through automatic ramps that previously can be programmed the value of voltage and the execution time of these.
