摘要：

To overcome the disadvantages of the large torque ripple and the non-constant switching frequency caused by hysteresis error control in direct torque control(DTC) for switched reluctance motor(SRM), a scheme of deadbeat-flux control(DB-FC) is put forward. By analyzing the basic principle of SRM, the voltage commands of DB-FC were deduced theoretically, and the voltage vector used to compensate the torque and flux in one control period was obtained, which can achieve the quantitative adjustment of flux linkage. Then, the voltage vector obtained was synthesized by space vector pulse width modulation and applied to SRM to achieve the tracking of flux-linkage in a sampling cycle, which avoids the overcompensation of DTC. Moreover, the system used a three-phase 12/8 pole SRM as the control object and compared the simulation and experimental results of DB-FC and DTC. Simulation and experimental resluts show that the DB-FC algorithm can minimise the torque ripple of SRM. DB-FC also has an excellent speed regulation performance and a good dynamic response capability. Furthermore, its calculation amount is small and easy to be implemented. © 2019, Harbin University of Science and Technology Publication. All right reserved.
