   A PI resonant current controller for an open-end winding induction machine fed by an indirect matrix converter
By Javier RIEDEMANN [View]
[Download]

Abstract: In this paper, a control strategy intended to eliminate any DC voltage offset caused by a common-mode and zero sequence voltage reduction modulation, from the machine terminals, is presented. In order to achieve that goal, a PI resonant controller is proposed to control the machine currents. Simulation and experimental results are presented and discussed.

   An Electrolytic Capacitor-less IPMSM Drive with Input Current Shaping Based on the Predictive Control
By Shengxiexian XUAN [View]
[Download]

Abstract: The control for a low-cost converter which consists of a half-bridge controlled rectifier and a four-switch three-phase inverter with two small film capacitors is presented, where a predictive controller is proposed to handle the large DC link voltage fluctuation, and a leading-angle flux-weakening method is used to control the converter to accomplish high speed operation of the IPMSM. Simulation results verify the effectiveness of the proposed methods.

   Analysis and Compensation of Band-Pass-Filter Delay for a High Frequency Signal Injected Sensorless Control
By Sang-il KIM [View]

Abstract: This paper proposes the phase delay compensation method of the analog filter used to enhance themeasuring performance for sensorless control based on high frequency signal injection. An inherentdelay effect caused by a band-pass-filter has a negative impact on the position estimation for a signalinjected sensorless control, and thus requires a proper compensation. In this paper, the delay effect isinvestigated theoretically, and its compensation method is proposed. Several verifications by thesimulations is presented.

   Optimum Efficiency Control of Interior Permanent Magnet Synchronous Motors in Drive Trains of Electric and Hybrid Vehicles
By Wilhelm PETERS [View]
[Download]

Abstract: In automotive traction applications the interior permanent magnet synchronous motor (IPMSM) is preferentially chosen as traction drive due to its high torque and power densities. In drive trains of electrical vehicles (EV) and most hybrid electrical vehicles (HEV) the traction motor is operated in torque controlled mode. In a field-oriented control scheme an operation point selection strategy is required to choose appropriate current setpoints to generate the requested torque with high precision and optimal efficiency. In this paper the potential to improve the efficiency by operating a motor with minimum overall losses instead of minimum current per torque is investigated. The interaction between the motor's loss characteristic, the impact of the voltage limit and the relevance of operation points for vehicle operation is explored theoretically and based on loss measurements. It is shown, that the losses can potentially be reduced at medium to high motor speeds with moderate torque requirements. This operation range corresponds to traveling with constant medium to high speed and slight acceleration and deceleration in electric vehicles. As well most operation points of the New European Driving Cycle (NEDC) and the Worldwide harmonized Light vehicles Test Procedure (WLTP) are in that operation range due to the moderate accelerations and decelerations in both driving cycles.
