Earlier studies have pointed out the limitations of conventional inverters, especially in high-voltage and high-power applications. In recent years, multilevel inverters are becoming increasingly popular for high-power applications due to their improved harmonic profile and increased power ratings. Several studies have been reported in the literature on multilevel inverters topologies, control techniques, and applications. However, there are few studies that actually discuss or evaluate the performance of induction motor drives associated with three-phase multilevel inverter. This paper presents then a comparison study for a cascaded H-bridge multilevel direct torque control (DTC) induction motor drive. In this case, symmetrical and asymmetrical arrangements of five- and seven-level H-bridge inverters are compared in order to find an optimum arrangement with lower switching losses and optimized output voltage quality. The carried out experiments show that an asymmetrical configuration provides nearly sinusoidal voltages with very low distortion, using less switching devices. Moreover, torque ripples are greatly reduced. © 2010 IEEE.

This paper proposes a traction drive system for electric vehicles (EVs) with two separate induction motor drive-based wheels. In this case, an electric differential (ED) is developed. To handle EV stability while cornering or under slippery road condition, the proposed traction drive uses direct torque control and an adaptive-flux-and-speed-observer-based algorithm. EV-specific experimental tests on a digital signal processor TMS320LF2407 are carried out to show the effectiveness of the proposed adaptive ED in terms of robustness and stability. © 2010 IEEE.

International Review on Modelling and Simulations | Year: 2011

This short paper deals with the transition performance improvement of a sensor fault-tolerant controller devoted to automotive applications. Indeed, improvements are brought over a previously developed technique that exhibit abrupt changes in the torque if a sensor fault is detected and after a transition from a control technique to another one [1]. The Fault-Tolerant Control (FTC) system firstly concerns the sliding mode control technique since better performances are obtained with an encoder to get the speed information. In the event of unavailability of the speed sensor, a sensorless fuzzy control technique is applied. In the proposed active fault-tolerant control approach a short and a smooth transition are achieved from the encoder-based control technique to the sensorless one using an appropriate fuzzy logic decision approach. © 2011 Praise Worthy Prize S.r.l. - All rights reserved.

Vehicle emission reduction has been a research objective for many years, by improving fuel economy and energy efficiency. Therefore, this paper presents a fuzzy logic controller for a Parallel Hybrid Electric Vehicle (PHEV). The PHEV required driving torque is generated by a combined contribution from an Internal Combustion Engine (ICE) and an Induction Motor (IM). The proposed Fuzzy Logic Controller (FLC) is designed based on the desired driving torque and the batteries State of Charge (SoC) with the objective to minimize fuel consumption and emissions, while enhancing or maintaining the PHEV driving performance characteristics. The fuzzy controller output controls the ICE throttle angle degree to achieve operation in a high efficiency region. The induction motor is sized to supply peak power to meet the load power requirement of the PHEV. The proposed PHEV fuzzy controller is implemented and simulated via the advanced vehicle simulator ADVISOR using the European urban (ECE-15) and sub-urban (EUDC) driving cycles. Simulation results reveal that the proposed fuzzy torque distribution strategy is effective over the entire operating range of the vehicle in terms of performance, fuel economy, and emissions. © Copyright 2011 IEEE - All Rights Reserved.

This paper presents the experimental implementation of sensorless direct torque control of an induction motor based electric vehicle. In this case, stator flux and rotational speed estimations are achieved using an extended Kalman filter. Experimental results on a test vehicle propelled by a 1 kW induction motor seem to indicate that the proposed scheme is a good candidate for an electric vehicle control. © 2010 Praise Worthy Prize S.r.l.

In this paper, we present a new Direct Torque Control (DTC) scheme for induction motors using a three-level neutral point clamped (NPC) voltage source inverter (VSI). In order to develop high dynamic performances, we propose a new approach, in which we enhance the responses of the torque and the flux with optimal switching strategies. Serious problems caused by significant fluctuations in the middle point of the three-level inverter. As consequence to these problems, we obtain an asymmetric inverter output voltage with a non-zero average value. Our proposed solution uses a hysteresis comparator to regulate the input voltages of the three-level NPC inverter. An enhanced direct torque control "EDTC" scheme is simulated with DC voltage source balancing for an induction motor. Our obtained results demonstrate high dynamic and stability performances. ©2010 IEEE.

This paper presents a hybrid cascaded H-bridge multilevel motor drive direct torque control (DTC) scheme for electric vehicles (EVs) or hybrid EVs. The control method is based on DTC operating principles. The stator voltage vector reference is computed from the stator flux and torque errors imposed by the flux and torque controllers. This voltage reference is then generated using a hybrid cascaded H-bridge multilevel inverter, where each phase of the inverter can be implemented using a dc source, which would be available from fuel cells, batteries, or ultracapacitors. This inverter provides nearly sinusoidal voltages with very low distortion, even without filtering, using fewer switching devices. In addition, the multilevel inverter can generate a high and fixed switching frequency output voltage with fewer switching losses, since only the small power cells of the inverter operate at a high switching rate. Therefore, a high performance and also efficient torque and flux controllers are obtained, enabling a DTC solution for multilevel-inverter-powered motor drives. © 2006 IEEE.

The Proton Exchange Membrane Fuel Cell (PEMFC) is being investigated as an alternate power source for various applications as transportation and emergency power supplies. Fuel cell systems are characterized by high costs and complex auxiliary devices. For this reason, a fuel cell emulator can be used as a suitable and economic alternative to a real one for developing and testing a fuel cell power conditioning system. The fuel cell emulator must be able to reproduce the FC nonlinear output voltage-current characteristic. This paper proposes then a possible solution to emulate a PEMFC system by using a DC-DC converter. The fuel cell system, including all its auxiliaries and related control systems, is emulated by a full-bridge converter experimentally achieved and controlled in the DSP2812 environment. The converter-based system allows the behavior of any fuel cell to be easily emulated and can be used in laboratory as a low-cost system for design and experimental purposes since only a DC-DC control modification is necessary. © 2011 IEEE.

This paper deals with hardware-in-the-loop simulation of urban electric vehicles. The proposed platform, which is expected to be used for electric vehicle prototyping, is very simple and effective. Indeed, the induction motor-based powertrain is coupled to DC machine-based load torque emulator taking into account the electric vehicle mechanics and aerodynamics. Experiments are carried-out using the New European Driving Cycle (NEDC) to show that the proposed hardware-in-the-loop simulation system is effective and provides a simple configuration for prototyping electric vehicles. © 2012 IEEE.
