Title : Servo tracking system that controls on the basis of DSP
Abstract
First,the paper introduces according to the DSP of servo tracking the hardware of the system to constitute the principle, and to three the segments of frequency carried on the analysis. Secondly, it constitutes system, establishes mathematical simulate model to evaluate the dynamic and static tracking error. Then, by introducing the equivalent compound control to improve the tracking ability. By using Lay-lead compensation, the tracking capability of the system is promoted to track fast moving targets at maximal angular-velocity and maximal angular-acceleration, while the maximal tracking error is less than 6.
In the end, Matlab/Simulink verifies the proposed methods. The results are much more like the theoretical analysis. The lag-lead compensation of speed and position can indeed improve the static and dynamic state properties of system.
