Single current loop control method of current source inverter for permanent magnet synchronous motor

The invention discloses a single current loop control method of a current source inverter for a permanent magnet synchronous motor, relates to the field of motor driving control, and provides a new scheme for driving of the current source inverter for the permanent magnet synchronous motor. Compared with a traditional permanent magnet synchronous motor voltage and current double-closed-loop control system driven by a current source inverter, the permanent magnet synchronous motor voltage and current double-closed-loop control system has higher current loop bandwidth and further has excellent dynamic performance. According to the single current loop control method of the current source inverter for the permanent magnet synchronous motor, a traditional voltage closed loop is removed, a single current closed loop control system is adopted, system resonance is suppressed by virtual impedance compensation, the bandwidth of the current loop is increased, and the response speed of the system is increased. 本发明公开了一种永磁
