The mathematical model of liquid crystal steering system is built. For improving convergence speed  the adaptive controller based on posteriori estimation errors RLS lattice filter is designed  which not only achieves fast adaptation  but also reaches optimal steady-state disturbance compensation. Finally  the simulation results show that this control scheme is valid and feasible.

The form of composite triangular and rectangular and the combination of open and closed back was explored in the lightweight design. A new kinematic mount and flexible structure in axis is used to hold the mirror around the lateral surface. The structure can minimize distortions induced by coefficient of thermal expansion mismatch among the materials. This eliminates the bending of the integral mount under the weight of the mirror. Optical performance of the mirror was analyzed under gravity load and temperature load using finite element method. Predicted surface figure error based on the removal of bias  tilt and power was calculated using an in-house Matlab script for mirrors. The pointing mirror assembly was tested using open loop servo control. And the surface figure was checked using interferometer. Surface figure accuracy is better than 1/30 ( 632.8nm  rms). The results show that the kinematic mount induces minimal figure error on the optical surface. 2011 IEEE.
