Description:
In this paper, new scheme of direct torque control of induction motor for
electric vehicles is proposed and the results of an investigation into suitable
torque control schemes are also presented. The electric vehicle drive consists
of rewound induction motors and a three-level IGBT inverter. The schemes
investigated are Field Oriented Control, Direct Torque Control (DTC), and
DTC using Space Vector Modulation. The results of Matlab - Simulink
simulations and a comparison between the control schemes are presented. It is
found that the DTC using Space Vector Modulation scheme is best for this
application. Platform: |

Description: This work is aiming to study and control of drive train of an electric vehicle based on doubly fed induction
machine (DFIM), the power structure of this machine and the control strategy applied allow operating over a wide
range of speed variation, for both applications: engine and recovery. Therefore the power of the machine can reach twice its rated power. After modeling different parts of the drive train a numerical simulation in MATLAB / Simulink is carried out. The results show the good performance of the vector control, and the structure of power applied to the DFIM. Platform: |

实用的永磁同步电动机驱动系统-Electromechanical sensors are commonly used to obtain rotor position/speed for high-performance control of interior permanent magnet synchronous machines (IPMSMs) in
vehicle systems. However, the use of these sensors increases the cost, size, weight, wiring complexity and reduces the mechanical robustness of IPMSM drive systems. These issues, together with
some practical requirements, e.g., wide speed range, extreme
environment temperature, and adverse loading conditions, make a sensorless control scheme desirable. This paper proposes an extended back electromotive force (EMF)-based sliding mode
rotor position observer for sensorless vector control of IPMSMs.
Based on filter characteristics, a robust compensation algorithm is developed to improve the performance of the sliding-mode observer (SMO). Multistage-filter and dual-filter schemes are designed to further improve the steady-state and transient performance, respectively, of the compensation algorithms. The proposed SMO and c Platform: |

this approach would provide both a dynamic uation of urban traffic flows and a dynamic redistribution of traffic flows across
