Field oriented controlled permanent magnet synchronous motor drive for an electric vehicle

Abstract

<span lang="EN-US">The paper describes field oriented control strategy with space vector pulse width modulation technique of permanent magnet synchronous motor drive system for an electric vehicle. At first, mathematical models of the motor and the drive system for electric vehicle are presented. In order to obtain high performance drive and maximum motor torque, field oriented control strategy and space vector pulse width modulation technique method are applied to drive system in next section. Speed controller design utilizing the popular zero-pole elimination approach causes large integral constant time in case of small rotational damping constant. The desired-transient-response-based approach is employed to overcome the problem. Performance indices include overshoot, undershoot, steady-state speed error, and total harmonic distortion of stator current, are employed to assess the drive systems with two speed controller design methods. Theoretical assumptions are confirmed via simulations and criteria in MATLAB/Simulink environment.</span>

Conceptual Framework for Modelling of an Electric Tractor and Its Performance Analysis Using a Permanent Magnet Synchronous Motor

“…Similarly, the proposed method produces a torque overshoot of 25% of the reference torque and it settles 0.025 s. Compared to Refs. [43,53], the torque overshoot (13% and 7.8%) is a bit higher. However, this algorithm is applied to off-road electric tractor operations, whereas it has traditionally been applied to on-road electric vehicle operations.…”

“…Whenever there is a change in the reference speed, the actual measured speed produces an overshoot of 3.5% and it settles at 0.01 s, whereas that of Refs. [52,53] produces an overshoot of 15% and 6.3%, respectively. Similarly, the proposed method produces a torque overshoot of 25% of the reference torque and it settles 0.025 s. Compared to Refs.…”

Energy management strategy for photovoltaic powered hybrid energy storage systems in electric vehicles

“…Numerous power conversion and management approaches have been examined so far, and both their advantages and disadvantages have been made plain. The future load demand for the cars is predicted by mathematical models that make use of state-of-the-art based techniques motivated by power system optimized performance [16]. A four-port bidirectional buck-boost converter (FPB3C) designed for EV was proposed by Katuri and Gorantla [17].…”
