Research Of DC Motor's Position Control Based On DSP

In the process of flighting objects being measured and tracked by O-E theodolite,the background of the objects changes ceaselessly,and the lum of targets'surface changes with it.In order to keep the lum of targets'surface invariable and not be affected to its variableness, we often tune it up with filter-patch(or density-plate) and spectrum-patch.So the control of their position seems very important especially.According to it ,a soluting of digital control system of DC motor using TI's TMS320LF2407 is presented in this paper.This control system includes two closed loops,which are position loop and velocity loop.A detailed design scheme of this digital DC motor control system'hardware,and some important functions blocks of data processing and power drive board are introduced.This paper introduces the design of DC servo systems'compensation based on frequency and have a simulink study. Programs are written in C and Assembly language and are debugged successfully in both software and hardware.In the end the result and analysis of experiment is given.
