A neural network adaptive fuzzy controller for optical lens grinding and polishing control was constructed. At the same time, a model of the grinding and polishing machine model for the dynamic estimation of lens aperture was established. The controller uses gradient descent learning algorithm to automatically adjust network weights and membership functions, so that the optimal membership function can be obtained. The system has a good self-adaptive learning function, the simulation results show that the control performance is better than the ordinary fuzzy control.
