摘　　要：工件在抛光过程中,无论为延长抛光带的寿命,还是为提高抛光的效率,工件与抛光带之间都存在一个最佳的压力问题。本文在气压传动基础上采用智能PID方法,实现了抛光带与工件之间压力的有效控制,不仅提高了压力控制的精度,而且提高了自动化程度。During the course of polishing, there is always a best pressure point between workpieces and sand belt for the life of sand belt and the polishing efficiency. To solve this problem, the intelligent PID control theory based on the pneumatic system was applied. By this way, the pressure is properly controlled, and the degree of automation is also improved.
