Control Technique of Opto-electrical Tracking Servo Rrotary Table

A kind of opto-electrical tracking servo rotary table system of control principle is introduced, Adoption ex- changes the servo electrical engineering drive, revolve transformer feedback, ARM9 numeral controller, PWM power drive of project are put forward and researched. With application of increasing-model PID control strategy of front-feed of speed and torque, the target of high accuracy stable tracking servo system is realized. To the system hardware electric circuit, control the calculate way, software process, a introduction is made in detail. The system makes use of ARM9 abundant of slice top resources, the biggest simplification system structure. Experiment shows, system adoption of control the strategy makes the system acquire higher tracking accuracy and better dynamic state quality.
