Abstract

This paper proposes a novel autonomous decentralized system (ADS) for controlling high power LPMSM. The system decentralizes a control system into several subsystems, thus the power supply and power electronic devices of the control system can be replaced by smaller ones, and the better fault tolerance of the system can be obtained. We first study the architecture of the ADS for LPMSM, then study the mathematical model of the LPMSM with decentralized stator coils. Finally, the fault model of the system is analyzed and a fault-tolerance design based on redundancy is proposed. The experimental results show that this method is effective for LPMSM control; excellent current control and fault tolerant feature of the system confirm the validity of the proposed system.
