    Abstract: A vehicle boom barrier gate system is one of
the recently developed technologies operating at the
entrances to the restricted areas. This study aims to design
and control of vehicle&#146;s boom barrier gate system using
robust augmentation technique. H<sub>2</sub> optimal and H&infin;
synthesis controllers are used to improve the performance
of the system. The open loop response analysis of the
vehicle boom barrier gate system shows that the input of
the system need to be improved. Comparison of the
vehicle boom barrier gate system with H<sub>2</sub> optimal and H&infin;
synthesis controllers have been done to track a set point
desired angular position using a step and operational open
and close input signals and a promising results have been
observed.
