The Adaptive Optics Laboratory of the University of Victoria has build a LGS SH-WFS test bench for the Thirty-Meter-Telescope project and its AO system, NFIRAOS. The UVic AOLab has recently shown the ability to track Na profile induced aberrations while correcting for turbulence aberrations. The UVic AOLab has started the second phase of development of its LGS SH-WFS test bench. This next step consists in adding the Truth WFSs into the current bench design and in modeling and implementing the algorithms which blends the data coming from the variousWFSs. This paper shows the various components of the control architecture of NFIRAOS LGS wavefront sensing process. A first simulation shows the stability of the proposed control architecture and demonstrates that the DM is kept away from reproducing the LGS aberrations.
