Study on a kind of antenna servo system

A new kind of design and achievement antenna servo system based on 80C196 is developed. On the base of particular introduction of several AC servo control technologies, the Permanent Magnet Synchronous Machine is adopted as the driver motor. To reach the achievement of a high and steady precision of the system, an absolute position photoelectric encoder is used as the feedback device, and the closed loop control mode including position feedback, velocity feedback and current feedback is degned for the driver motor. The Object-oriented method is used for the system analysis and study. The hardware and software of the system have been designed and debugged on the CPU of special motor controller-80C196MC. Then the experimentations are done, which show that the system is steady-going and reliable and the scheme is reasonable and feasible.
