Soft Starting of Medium Voltage Induction Motors With Fuzzy PD Control

摘要

A novel fuzzy control soft starting medium voltage induction motor is presented in this paper, Introduced the principle and the design of software and hardware on the medium voltage soft starter for asynchronous motors. According to analysis of the starting characteristic of induction motors, discussed a design method of medium voltage induction motor soft starting based on fuzzy Proportional-Differential (PD) control. Through measuring the input current, fuzzy control and PD control are used in the different phases of starting process to get the best control results.
