Fuzzy torque control for induction motor

摘要

In this paper, authors present a kind of fuzzy torque control system for induction motor, and apply error of stator flux, error of motor electromagnetic torque and positional angle of flux as fuzzy variable, voltage vector of inverter was selected through fuzzy decision. In this way, it improves system response speed during the start-up and a abrupt change in command torque. The simulation results show that fuzzy torque control system meet demand better for fast response.
