Electric Vehicles (EV) or Hybrid electric vehicles (HEV) require an electric motor which has high power density, high efficiency and a wide constant power operating region with flux weakening (FW) capability. Three phase Interior Permanent Magnet Synchronous Motors (IPMSMs) meet these criteria and are hence used in most commercial electrified vehicles. This work presents analysis, control system design...
This paper addresses the design of an induction motor for electric vehicle applications. The motor is required to give very high transient torque during accelerations will being efficient under steady state operation. The paper discussed the required torque-speed envelope and develops a design which is suitable. The analysis techniques includes the use of a spreadsheet design package, a finite element...
This paper proposes a new permanent-magnet vernier (PMV) in-wheel motor to meet the new demands arising from in-wheel electric vehicles. It can offer the advantages of light weight, compact size and low-speed high-torque operation. The mechanical gear can be removed by introducing flux-modulation poles. By using the time-stepping finite element method, the performance of the proposed machine can be...
In electric automotive traction drives an optimal utilization of the DC-bus voltage in the wide flux weakening range is crucial. At the same time a voltage margin is required to ensure the stability of the inner current control loop. An adequate trade-off between these conflicting objectives is obtained by employing a superimposed voltage controller that is activated during flux weakening operation...
A novel H∞ robust regenerative braking control strategy for electric vehicle (EV) is presented after different regenerative braking control strategies are discussed in this paper. Research work is done under different conditions namely variable battery voltage and variable load rotational inertia, separately. A comparison between conventional PID control and H∞ robust control is done when they are...
There are many uncertainty factors when the electric vehicle (EV) drives in the complicated variable circumstance, it make the control effect of some control modes non-ideal. To ensure the robustness of the closed-loop system under the presence of uncertainties, such as parameter perturbation and unknown model dynamics, and to minimize the effect of disturbances, the mu synthesis robust control is...
Indirect field oriented control (IFOC) and direct torque control (DTC) have been widely commercialized in induction motor drives, with each being favored by its supporters. In this paper, the dynamic performance of these drives for an electric vehicle application is examined, and sensitivities to parameter variations affecting this dynamic performance are explored. Key performance measures include...
Battery-powered electric vehicle appear to be one of the viable solutions for the growing concerns for environmental protection and the fast rate of depletion of world fuel oil supply. This type of vehicle can become a viable alternative to the internal combustion engine only if they are able to meet certain reliability, safety, performance, and cost criteria. In addition, this type of electrical...
Electric vehicle drive systems require fast torque response and high efficiency over a wide range of velocities. In this paper, a fast torque response control strategy suitable for the region above the base frequency is proposed based on an analysis of the impact of the efficiency optimization strategy on dynamic response. The operation characteristics of induction motors in typical drive cycles are...
