现有数控小工具光学表面成形技术的控制模型是线性模型,它在应用中存在确定加工参数周期长、精度低、耗资大等困难。为此提出一种智能控制模型——改进型自适应模糊控制模型,具有自学习功能,并且可充分利用专家语言信息和数据信息。采用该模型仿真抛光一周期,面形P-V值收敛了30%左右。

Computer controlled optical surfacing (CCOS) is one of the most important methods in fabrication of aspheric surface. In this paper, considering manufacture of aspheric lens, an improved adaptive fuzzy algorithm based on semantic and numerical inference is developed and a prediction system is built up. The simulation demonstrates the validity of the method.
