A Servo Control System Based on Fuzzy PI Method for Transverse Flux Machine in Mechanical Press

摘要

A control method for servo control system of Assembled Claw Pole Stator Transverse Flux Machine (ACPTFM) by controlling the armature current Root-Mean-Square (RMS) and the angle between armature current and no-load EMF is proposed in this paper. The servo control system of ACPTFM is composed of a series of closed-loop controllers, and the most complexity design of speed controller is described in detail. Fuzzy adaptive PI control method which integrates the advantages of fuzzy control and PI control is adopted to design the speed controller. Experimental results show that it can improve the system dynamic response and steady state accuracy.
