A methodology to design the dynamic model taking the mutual inductance into account for the switched reluctance motor (SRM) drives is proposed in this paper. The overall consideration is focus on the current control compensation strategy that related to the practically existing unmodeled parameter, the mutual inductance, to improve the drives performance. A mutual inductance related expression is discussed and then an optimum searching method, chosen for ease-of-applying, is utilized for solving the key parameter owning on-line computational procedures potentials. By the presented model based on the motor characteristics analytical opinion, the relationship between the compensation current command and the neglected effect of the drives output can be established. The effectiveness of this model is demonstrated by the comparison with/without the dynamic model being involved.

The simple evaluation model utilizing the selective parameters for the preliminary analysis for magnetic refrigerator (MR) development is proposed in this paper. The magnetocaloric effect and the related magnetic field applied for MR are also discussed. The model and system analysis following the algorithm expressions and the material characteristics required for MR are arranged and derived in related evaluation terms. The simulation results verify the feasibility and applicability for this simple evaluation model. (C) 2004 Elsevier B.V. All rights reserved.

A novel method, the simple reluctance-based efficiency control for the switched reluctance motor drives, is proposed in this paper. This concept is realized by programming the ratio of current command to phase voltage, and to utilize the time-dependent derivatives of equivalent magnetic inductance obtained from reluctance-related opinion. The algorithms and computational procedures are derived and completed taking equivalent magnetic inductance into consideration. Simulation and experimental results demonstrated the validity of the capability for efficiency regulation of the proposed method. (C) 2004 Elsevier B.V. All rights reserved.

in this paper, an analytical methodology utilizing fuzzy neural network (FNN) that improves evaluation capabilities for switched reluctance motor (SRM) drives is presented. Firstly, a FNN is applied to establish the mapping relation among the driving current, rotor angle, and equivalent inductance by the information obtained from the SRM characteristics measurements. Then two FNNs, which own the competence to do partial derivative computation, are constructed herein to complete this FNN-based analysis model. The computation results under different speed commands and load conditions respectively verify the proposed analysis opinions.
