We describes the status of AO test bench, which is developing at the Adaptive optics Lab, V.E. Zuev Institute ofAtmospheric Optics of the Siberian Branch of the Russian Academy of Sciences (IAO SB RAS), Tomsk, Russia tosimulate predictive algorithms of wavefront adaptive correction. The description of the optical and mechanical design,components AO bench, and the working principle and first experimental results are presented. The current AO test benchconsists of laser source, two deformable mirrors with 59 actuators and 56 mm diameter (Visionica Ltd., Russia), twotip/tilt mirrors (IAO SB RAS, Russia), Shack-Hartmann Wavefront Sensor (WFS), which we specially designed, and ascience camera for the evaluation of the performance. The user derived aberrations are introduced using a onedeformable mirror and corrected by another deformable mirror. The tip/tilt mirrors are used for predictive control of thelow-order wavefront aberrations related such as vibrations.
