Recently, many examples of practical applications of the motors with reluctance torque, such as IPMSM, RM, etc are reported. However, the problems of the torque ripple produced by the IPMSM, are also presented. The main reasons of the torque ripple generation are the structural imperfectness of the IPMSM and its control system, such as the cogging torque of the motor, the dead time of inverter, sensors offset, imbalance and non-lineanty, and so on.<br/> In this paper, authors propose a suppression control method of the torque ripple for IPMSM utilizing the repetitive control with the Fourier transformer and a vibration signal detected by an acceleration sensor attached to the motor frame, considering periodicity of the motor torque ripple An experimental system to simulate the compliant mechanical frame is constructed, and the effectiveness of the proposed method is confirmed by experimental results.<br/>

This study proposes a novel frame anti-vibration controller for position sensorless PMSM drive application. This controller is called specific component reduction controller (SCRC). SCRC can function without an accelerometer and can achieve speed variable control. This study mainly comprises the following phases. First, the position sensorless control method will be provided. Second, the frame vibration model and load torque ripple will be shown. Third, SCRC will be discussed and its stability will be analyzed. Finally, experimental results show that SCRC can achieve speed variable anti-vibration control and compensate target frequency torque ripple.

Permanent magnet synchronous motors(PMSM) have been receiving much attention due to their high effi-ciency. Usually, an inverter is used to drive the PMSM. In conventional current control systems, the inverter is regarded as an ideal amplifier. However, there exist various constraints such as voltage saturation in current transient response and output nonlinearity in over modulation. Inaddition, an output of the inverter is limited to discrete values in aprecise sense. Thus, the system has an a ture of a hybrid dynamical system. In this paper, we propose a novel model predictive control(MPC) based current control system to improve performance in cases where the inverter can not provide the appropriate output. In MPC, a steady state error often occurs due to the modeling error. In order to over come the problem, we extend the model in which the accumulation of the steady state error is included. The effectiveness of the proposed method is shown through simulations and experiments.
