Research on Synchronization Control of Dual-Motor Driving for Large Rotary Car Dumper


Article Preview

Car dumper is an important material transport equipment which has characteristics such as large structure, heavy duty, low frequency operation, stop-and-go and recurrent excursion of machine barycenter. This paper researched implementation of synchronization control. A fuzzy controller is added between two channels of dual drive subsystem. Based on coordinated control principle and achieving the goal of difference minimum of corresponding state of two subsystem, a fuzzy correction control program using in-phase error non-uniform common feedback is adopted to make the output of two synchronous subsystem consistent basically, which increase response speed of system to synchronous error, reduce synchronous error of dual drive subsystems effectively, ensure the consistency of car dumper dual drive, solve the recurrent mechanical failure caused by inconsistency of dual drive and enhance the steady reliable operation of car dumpers. The synchronization control strategy presented by this paper provides favorable guarantee for synchronization precision of multi subsystem in large rotary equipments and at the same time explores new ideas for other synchronization control systems.
