This paper presents the digital PI control method for design and simulation of a high precision limited angle brushless torque motor control system in Field Programmable Gate Array device (FPGA). The direct drive structures which are widely applied in many servo control fields. Matlab Xilinx System GeneratorR toolbox based on Fixed-Point Arithmetic is used to design the digital PI controller using DSP architecture  plot the responses of the control system and generate the VHDL source code. The control system model consists of a digital PI  a real LABTM  and a real absolute Inductosyn  encoder to rpm and position blocks. Through loading generated codes in process of the simulation that built by the digital discrete model  it is verified that the rising time of current loop is only 1.2ms  and rate loop is 8ms  overshoot is rarely 4.2%. Finally  the comprehensive positioning accuracy of system can reach up to 5 arc sec  and the rate jitter achieves 5% with the 4 arc sec accuracy absolute Inductosyn.

The position of focal plane will be changed because of temperature fluctuation and vacuum environment. In order to make the telescope work well  positioning accuracy of the mechanism is 0.008mm. The performance satisfies the need of precision  a focusing mechanism is needed. To majority of large space-based telescopes  and the scheme design is reasonable and practicable. 2012 IEEE.  the general way to do this would be to use a reflector  which was located in the backfocal distance. One of typical schemes of this mechanism was introduced  however  because of the big axial size  the mechanism can't be used when the size of the enclosure was limited. A new type of focusing mechanism was introduced  which has such advantages of small size  high accuracy and low mass. The design and test methods had been discussed. According to the results  the repeatability positioning accuracy is 0.0025mm
