Hybrid-excited flux-switching (HEFS) machine is a relatively novel brushless machine having magnets, armature windings and field windings in the stator, as well as a simple and robust rotor. In this paper, the control strategies for the proper injection of field currents are proposed and implemented by a simulated model based on Matlab/Simulink. The predicted performance confirms the excellent flux-regulation...
Much attention has been recently drawn towards switched reluctance machine (SRM) based vehicle propulsion systems. This is especially due to the excellent extended speed features of SRMs for electric/hybrid electric vehicle propulsion applications. However, the inherently large torque ripple and highly nonlinear characteristics of SRMs present significant challenges from the controller design standpoint...
Cornering stability of 4 wheel drive hybrid electric vehicle has been analyzed and improved, where the front motor and the rear motors are used to drive the vehicle. For the control of the motors, a model reference sliding mode controller is designed to generate the additional yaw moment for the vehicle. The algorithms for the motor driving and the yaw rate control for the 4 wheel drive hybrid electric...
This paper presents a hybrid controller for hybrid electric vehicles using hybrid system theory. The hierarchical control structure of parallel hybrid electric vehicle (HEV) is introduced first and the drive control problem of the vehicle is formulated using hybrid system theory. State machine theory is applied to solve the problem of vehicle operating mode transitions. Then a fuzzy torque distributor...
