For the characteristic of the ring permanent magnet torque motor used in direct drive numerical control round table suffering from the effect of load disturbances and parameters variations, a multi-objective mixed H2/H∞ static output feedback controller, which makes all poles of the closed-loop system be located within a prescribed linear matrix inequality region D to achieve pole placement, is designed based on LMI.

针对直接驱动数控转台用环形永磁力矩电机易受负载扰动及自身参数变化影响的特点，文中基于线性矩阵不等式(linear matrix inequality， LMI)，设计了一个多目标混合H2/H￥静态输出反馈控制器，该控制器可使闭环系统的极点均落在预先选定的线性矩阵不等式区域D内来实现极点配置。

As the address of EEPROM, which was used for looking2up table, the information of octant and signals of magnetic encoder which were converted by A /D converterwere dealt by FPGA. And the frequencymultip lication formagnetic encoderwas comp leted. So the resolution and accuracy ofmagnetic encoderwere imp roved, 4096 multip le frequencies can be achieved in per cycle.

同时利用FPGA对卦限信息和磁编码器输出信号的A /D转换信息进行处理，作为EEPROM的地址信息进行硬件查表，实现对磁编码器信号的倍频处理，从而提高了磁编码器的分辨率和测量精度，可实现每个周期4 096份的倍频。

To some problems of it, the design train of thought that only A/D, subdivision and counting circuit compose open-loop control system is proposed in this paper.
