Abstract:In order to solve the problem that the high-frequency signal injection is not flexible enough in the traditional maximum-torque-per-ampere (MTPA) control method, a novel signal injection method with variable frequency is proposed. The proposed method changes the action time of each voltage vector in space vector pulse width modulation (SVPWM) to generate a variable frequency signal, and directly injects the signal into the inverter to realize the MTPA. Since the variable frequency signal injection method is implemented in SVPWM algorithm, the frequency of the injected signal changes with the motor speed, which makes the selection of the signal frequency more flexible. Additionally, since the signal is directly injected into the inverter, the frequency of the injected signal does not interfere with the inherent harmonics in the motor. Hence, the bandwidth limitations of the current loop can be eliminated. The proposed method simplifies the part of signal analysis without reducing the tracking performance of MTPA points. Finally, the experimental and simulation results show that the method can accurately track MTPA points, and has robustness to torque and speed changes.
