“…The offset error causes harmonic current with synchronous frequency (1 f ). On the other hand, gain error causes harmonic current with double of synchronous frequency (2 f ) (1) (2) . Current control performance is degraded by this harmonic current and it also has an adverse effect to the higher control system, such as position control and torque control which require the control accuracy of current control subsystem.…”

A general-purpose inverter controls the output current using information from current sensors for high-performance motor control. However, these sensors outputs, however, have some gain and offset errors that depend on the peripheral components and the characteristics of the current sensor. These errors cause an imbalance in the output current, which causes a torque ripple. The torque ripple leads to many problems. The authors have proposed a periodic disturbance observer (PDO) as a control method for vibration suppression. The current sensor error causes a vibration with a specific frequency; thus, this paper proposes a current sensor error compensation method to apply the PDO for suppressing this specific frequency. This method can suppress the harmonic current in real time, and the current control performance can be improved by error compensation. This paper explains the proposed method and demonstrates the effectiveness of the proposed method through simulation and experimental results. In addition, this paper verifies the follow-ability of sensor error variation.

Interior permanent magnet synchronous motors (IPMSMs) are generally driven by current control based on a vector control system. Usually, in such a system, the harmonic current appears in the current control loop. Some harmonic current suppression control methods using repetitive control have been proposed. In earlier repetitive control techniques, the amount of memory for implementation was not considered explicitly. Furthermore, optimality was not ensured in our earlier studies. In this paper, we present a novel harmonic current suppression method using the generalized repetitive control. Compared with the conventional method, the proposed method achieves better control performance while taking into account the amount of memory for implementation. The effectiveness of the proposed method is verified through simulations and experiments.

“…In the method, each amplitude and phase for each compensation signal is searched online so that its corresponding harmonic current can be effectively suppressed. Not only for the harmonic current, but also for the frame vibration of motors, experimental results have been demonstrated using the repetitive control [4], [5], [6], [7], [8]. However, the amount of memory for implementation has not been considered explicitly in the method using the conventional repetitive control methods.…”

Interior Permanent Magnet Synchronous Motors (IPMSM) are generally driven by the current control based on the vector control system. However, there exist harmonic components in the current control loop. For the harmonic current, suppression control methods using a repetitive control have been proposed. In the conventional repetitive control, the amount of memory for implementation has not been considered explicitly. Furthermore, the control parameters determined in our earlier works does not ensure an optimality. In this paper, we propose a new control method of suppressing the harmonic current using the generalized repetitive control. Compared with the conventional method, the proposed method achieves better control performance while considering the amount of memory. The effectiveness of the proposed method is verified through simulations and experiments.
