Decoupled Current Vector Control of Dual Three Phase PMSM Drives with Two Independent Micro Control Units Utilizing Current Observer

This paper presents a coupling estimation based decoupled current vector control scheme for of Dual Three Phase (DTP) Surface Permanent Magnet Synchronous Motor (SPMSM) drive with two micro units (MCUs), to solve its inherent magnetic issue. Aiming an enhanced fault tolerance, the SPMSM utilized is redundant and modular system composed subsystems in terms three-phase inverters, sensing, controllers, respect each winding set DTP SPMSM. The along rotor position separately detected applied by individually assigned MCU. comprehensive modularity prevents interference between local conditions, thus improving tolerance capability. However, existing sets would deteriorate performance even cause instability whole without proper decoupling control. Previous studies adopted communication MCUs real time sampling sharing demanded Nevertheless, bandwidth becomes limiting factor design. Some general approaches not satisfy requirement implementation. To eliminate this undesirable limit, novel that utilizes observer estimate relevant proposed paper. As validated from experiment results, able decouple dynamic improvement so can be achieved communication, leading eventual
