Design and Achievement of the Antenna Servo System Based on 80C196MC

A new kind of design and achievement of the antenna servo system based on 80C196MC is developed.On the basis of particular introduction of several AC servocontrol 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 designed 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 experiments are done,which show that the system is steady-going and reliable,and the scheme is reasonable and feasible.
