Electric vehicle transportation system have gained increasing attention in recent years. Low weight, less volume and high efficiency are the main requirement of electric vehicles. Efficiency analysis of drive of electric vehicles is of major concern to increase its driving range per charge. This paper proposes Interior Permanent Magnet Synchronous Motor (IPMSM) Drive controlled by Field Oriented Control[1]...
For realizing real-time efficiency optimization control of interior permanent-magnet synchronous motor (IPMSM), the optimal currents (OCs) need to be computed real-timely. This paper proposes a method based on the projected dynamic system to find the OCs. Firstly, the efficiency optimization of IPMSM was regarded as a constrained optimization problem. And then, the optimization problem is classified...
The paper assesses the influence of driving cycles on the design optimizations of permanent magnet machines for electric vehicle traction applications with the objective to minimize total loss over a defined driving cycle while satisfying performance specifications and design constraints. With the help of an efficient optimization methodology and tool, the optimizations against New European Drive...
This paper examines the influence of lamination material on the performance of a flux focusing permanent magnet machine. This machine is designed for the traction of hybrid vehicles. The design optimization is performed by coupling a multi-objective particle swarm optimization algorithm with the finite element method. The optimization procedure is performed for three different lamination materials...
In view of the operation characters of permanent magnet synchronous motor (PMSM) for hybrid electric vehicle (HEV) application, efficiency optimization control strategy is needed to meet the demand of rapidity. An efficiency optimized vector control scheme is presented in this paper. The initial value of d-axis current can be achieved in any constant speed and torque operating point by loss model,...
