   Extended Straightforward Current Control for Permanent Magnet Synchronous Machines
By Andreas LISKE, Philipp HOFMEIER, Michael BRAUN [View]
[Download]

Abstract: This paper presents a direct, adaptive and parameter-free current control scheme for synchronous machines with excellent control quality and high dynamics. For magnetic anisotropic synchronous machines, it automatically allows easy identification of the rotor position angle in the whole speed range,making it particularly suitable for sensorless control.

   Model-based Voltage Phase Control for IPMSM with Equilibrium Point Search
By Takayuki MIYAJIMA, Hiroshi FUJIMOTO, Masami FUJITSUNA [View]
[Download]

Abstract: This paper presents a model-based design method of voltage phase controller for IPMSM with equilibrium point search. The voltage phase controller controls the torque with the output voltage phase only in high-speed region where the inverter output voltage amplitude is saturated. However, voltage phase control cannot achieve quick torque response because it is designed in defiance of transient characteristic. Due to the nonlinear characteristic between torque and voltage phase, precise model-based design have not yet been carried out. In this paper, a model-based design is proposed by the linearizing the relationship between torque and voltage phase. The analysis of the proposed model describes that the plant is a non-minimum phase system. Simulation results and experimental results show the effectiveness of the model-based design method.

   Robustness analysis of deadbeat, direct torque and flux control for IPMSM drives
By Jae Suk LEE, Robert D. LORENZ [View]
[Download]

Abstract: This paper presents robustness evaluation of deadbeat-direct torque and flux control (DB-DTFC) of IPMSM drives with respect to machine parameter variation. For performance comparison, current vector control (CVC), one of the most widely used control methods, is also implemented under identical operating conditions as DB-DTFC. As the metrics to evaluate dynamic performance of DB-DTFC and CVC IPMSM drives, command tracking is used to investigate torque command tracking performance and dynamics stiffness is used to evaluate disturbance rejection performance. In addition, the torque estimation accuracy of DB-DTFC and CVC is investigated with respect to parameter variation. Simulation and experimental results of robustness evaluation of DB-DTFC and CVC are presented in this paper. Furthermore, the dynamic robustness of DB-DTFC and CVC drives are evaluated via eigenvalue (EV) migration. Since an IPMSM drive is a nonlinear system, an operating point model of an IPMSM drive is derived for linear analysis of EV migration. Finally, the US06 Supplemental Federal Test Procedure (SFTP) automotive driving cycle is applied to investigate the EV migration of a test IPMSM drive over a wide operating space.

   Space Vector Modulation technique for common mode current reductionin Multiphase AC drives
By Mario PULVIRENTI, Giuseppe SCARCELLA, Giacomo SCELBA, Mario CACCIATO [View]
[Download]

Abstract: The paper presents a space vector based modulation technique able to reduce Common Mode Currents (CMC) in six phase integrated AC motor drives. The proposed modulation strategy performs a suitable selection of the inverter states in order to achieve a considerable reduction of the Common Mode Voltage (CMV) variations, with a slightly reduction of the DC bus utilization compared to the standard Space Vector Modulation (SVM) approaches; drives operating with the proposed modulation method still maintain same performance in terms of dynamic control.The entire analysis has been performed on a six phase motor configurations, supplied by a single two level multiphase inverter and the effectiveness of the theoretical study has been verified by simulation results.
