The Mode of Speed Control and Safety Discussion of the Permanent Magnet Cynchronous Elevator Based on Fuzzy Logic Control

The control mode of permanent magnet synchronous motor commonly used in traction elevator is analyzed, and the mathematical model of permanent magnet synchronous motor is introduced to obtain the relationship between motor torque and current parameter change. Then, combined with the fuzzy logic control principle, the fuzzy logic control mode of the permanent magnet synchronous motor used in the elevator is analyzed, the effect of the fuzzy logic control system is analyzed, and its impact on the safety performance of the elevator is discussed.
