(TU Delft DC systems, Energy conversion & Storage; Southeast University) Huang, Yunkai (Southeast University) Peng, Fei (Southeast University) Dong, J. (TU Delft DC systems, Energy conversion & Storage) Zhu, Zichong (Nanjing Tech University) Date 2022 Abstract This article proposes a discrete-time dynamic-decoupled current controller for an LCL-equipped high-speed permanent magnet synchronous machine with only the motor currents measured. The controller is designed in the synchronous coordinate based on a complex z-domain transfer function. The main contribution of the proposed current controller is the robust dynamic decoupling performance to achieve better transient behavior. Moreover, an effective coefficient selection method is developed to acquire sufficient phase margin and gain margin, even with the system parameters varying ± 50%. Additionally, the stable region of the LCL resonance with the proposed method is discussed. Finally, the effectiveness of the proposed method is verified by driving the tested motor to 100 kr/min.
