Study on Application of Fuzzy Control for Energy-Saving Starting of the Wound Rotor Asynchronous Motor

摘要

This paper deduces conditions for the wound rotor asynchronous motor to start with the maximum torque, from the electromagnetic torque equation for the three-phase asynchronous motor. The constant-current source circuit based on Boost is used to construct the topological structure for maximum torque starting, the combination of traditional PID and fuzzy control is applied to realize the constant-current control of Boost circuit, and a complete fuzzy control table is presented. Through simulation, it is testified that the Boost circuit has a good constant-current effect and achieved constant torque starting.
