Fixed Base Stable Servo Control

This thesis is derived from the moving target tracking sub-system, which is a part ofthe system with floating-observation-platform. The sub-system is designed to trackmoving target steadily in the condition of moving base.The steady servo system with moving base ineludes tWO parts. One is stabilization,the other is tracking. The system usury can make it with several servo Systems workingtogether. The article carries out the control of azimuth and height steadily just with twopiece of servo system.The article first introduce the design thinking and control theory of steady servosystem with moving base, pointing out the method which can convert the problem frommoving base to smile base with the tracking-line. Based on the image processing, thetarget information could be converted to tracking error, which carry out the steadytracking. Because of the non-linear and time-changing system, the article choose theillegible PID control method of self-controlling parameter to design the PID controller,and use the toolbox of MATLAB/SIMULINK to simulate experiment. In the debuggingof steady servo system, it can obtain perfect result with suppositional moving modelwhen the input is step, slope or sine wave.At last, on the basis of simulation, the experiment carried out the steady tracking ofmoving target with the image processing.
