Control of Variable Flux Reluctance Motor in Field Weakening Region
2021 International Aegean Conference on Electrical Machines and Power Electronics (ACEMP) & 2021 International Conference on Optimization of Electrical and Electronic Equipment (OPTIM), 2021In this paper, the operating point of variable flux reluctance motors (VFRMs) using voltage and current limits in the field weakening region is investigated. The voltage and current limits of VFRM, which depend on the current capacity of the inverter and the voltage limit of the inverter, are investigated by using MATLAB/Simulink. The d-axis and q-axis

Field-weakening control for an IFO induction motor drive
2002 IEEE Region 10 Conference on Computers, Communications, Control and Power Engineering. TENCOM '02. Proceedings., 2003The transient performance improvement for an indirect field-oriented (IFO) induction motor drive with field-weakening is studied in this paper. In the proposed method, the saturation effect of magnetizing inductance is considered by representing it using a fitted quadratic polynomial of flux current. The flux current command is composed of three parts,

Current Control for SPMSM in Field-Weakening Region Based on Final-State Control
IEEJ Transactions on Industry Applications, 2012SUMMARYSPMSMs (surface permanent magnet synchronous motors) are employed for many industrial applications. SPMSM drive systems should realize a quick torque response and have a wide operating range. For quick current response in the field‐weakening region, a new current control based on final‐state control (FSC) is proposed in this study.

Optimum-seeking field weakening control of induction motor drives
8th International Conference on Power Electronics and Variable Speed Drives, 2000The optimum-seeking (in the sense of maximisation of torque) field weakening control scheme proposed by Kim and Sul (see IEEE Trans. Ind. Electron., vol. 44, no.4, p.512-18, 1997) is developed further. The performance under imperfect field orientation conditions is investigated, and it is shown that an overestimated-rather than an under-estimated-model

Induction motor torque control in field weakening regime by voltage angle control
Proceedings of 14th International Power Electronics and Motion Control Conference EPE-PEMC 2010, 2010This paper presents a novel algorithm for the induction motor torque control in field weakening region. Proposed method insures maximum DC bus utilization and offers DTC performance through the stator voltage angle control. The algorithm is simple, without the outer flux loop nor the inner current loop.

Field-weakening in vector controlled and DTC PMSM drives, a comparative analysis
8th International Conference on Power Electronics and Variable Speed Drives, 2000The present paper gives a comparative analysis of field-weakening in vector controlled and direct torque control (DTC) permanent magnet synchronous motor drives. For this purpose, the fundamentals of these drives are discussed. The results of extensive simulations and a comprehensive set of experiments are given.
