Research on FFU Power Supply Based on Variable Universe Adaptive Fuzzy Control

Abstract

There are serious nonlinear, variable strongly coupling characteristic in traditional fan filter units (FFU) motor, and its electromagnetic relationship is hard to analyze. In order to solve these problems, and because the FFU motor has serious nonlinear, variable strongly coupling characteristic, a control system for FFU motor speed regulation is carried out based on the variable universe fuzzy theory, which can modify universe according to the change of inputs. The simulation analysin and experimental results are prposed and verified the power supply can more effectively achieve the FFU fan motor variable frequency speed regulation control than traditional methods and the performance of the proposed control strategy.
