Speed Control System of Inverter Using Fuzzy Neural Network

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for performing speed control using a fuzzy neural network having a dynamic expansion structure. The present invention relates to a speed setting unit (1), a speed controller (2; SC), a limiter (3), a vector operator (4), and a direct current / In the PI speed controller provided with the AC converter 5 and the speed measuring sensor 6 (PLG), the speed setting part 1 and the speed measuring sensor 6 are attached to the fuzzy controller 11 and the neural network controller 12. ) By connecting the output terminals of the fuzzy controller 11 and the neural network controller 12 (NNC) to the front end of the limiter 3, respectively, and adding the common fuzzy controller and neural network controller to the PI controller to be controlled. There is an advantage that can minimize the control error without being affected by the gain.
