Abstract

Closed-loop control system of three-axis tentative turntable based on programmable multi-axis controller (PMAC) is composed of turntable, PMAC, driver, motor and sensor. Obliquity sensor measured vibrational angle of X and Y axes of carrier was used as positional loop of the system, photoelectric encoder was used as the speed loop. The search and tracking of turntable was realized by Z axis. Control programs about horizontal stabilization of turntable and searching and tracking of azimuth axis were compiled with PMAC language. The PID parameter was adjusted in the order of proportion, integral and differential, and was decided by trying from small to large.
