摘要
分析了现有计算机数控光学表面成形CCOS的控制模型,即“线性移不变系统”。这是一种线形模型,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1/3左右。
The existing Computer Controlled Optical Surfacing (CCOS), i.e., linear and shift invariant system, is analyzed. This is a linear model. There are difficulties such as long period in determining processing parameters, low accuracy and large cost etc. in applications. For this reason an intelligent control model―an modified adaptive fuzzy control model with self-training function and capable of fully using expert language information and data information is proposed. If we model polishing period with this model, the P-V values of surface shape are reduced by a factor of 3.
