Design and Realization of Two-dimension TV Tracking Platform′s Servo Control System

Focusing on the problems of real-time and accuracy in the moving targets tracking system,the design and realization of the two dimension television tracking platform′s servo control system are introduced.The method of software position inner loop and speed external loop is introduced.Thus the system has good start up and anti-disturbing performance.The experiment shows that the angle speed of the system can be 0.01°～20°/s,the largest tracking error can be 3′.The main innovation of the paper is finding an improved PID algorithm′s position inner loop and hardware speed external loop.The algorithm can improve the system′s real-time performance effectively.
