Wound-rotor induction generators have numerous advantages in wind power generation over other types of generators. One scheme is realized when a converter cascade is used between the slip-ring terminals and the utility grid to control the rotor power. This configuration is called the doubly-fed induction generator (DFIG). In this paper, a vector control scheme is developed to control the rotor side...
Wound-rotor induction generators have numerous advantages in wind power generation over other types of generators. One scheme is realized when a converter cascade is used between the slip-ring terminals and the utility grid to control the rotor power. This configuration is called the doubly-fed induction generator (DFIG). A neuro-fuzzy vector control scheme was presented previously by the authors...
Permanent magnet synchronous machines (PMSMs) are the most popular motors being used as traction motors in the electric drive-train due to their high torque-per-ampere characteristics and potential for wide flux-weakening operation to extend the constant power range. This paper classifies and overviews the state-of-the-art flux-weakening control strategies for PMSMs. The advantages and disadvantages...
This paper presents a neural network (NN) based solution to optimize the efficiency of a switched reluctance motor (SRM) for hybrid electric vehicle propulsion at high speeds. Based on the high learning ability of NN, the NN controller learns off-line the relationship between switching angles (turn-on and turn-off angles) corresponding to maximum motor efficiency and SRM operating points (torque,...
This paper presents a neural network (NN) based solution to reduce torque ripple of a switched reluctance motor (SRM) for hybrid electric vehicle (HEV) propulsion. Based on the high learning ability of NN, the NN controller learns off-line the non-linear torque-current-angle characteristic under twophase excitation, and finds an appropriate phase current profile for torque ripple reduction in real-time...
