Interior Permanent Magnet Synchronous Motor Linear Field-Weakening Control
IEEE Transactions on Energy Conversion, 2016At nonlinear field-weakening control of interior permanent magnet synchronous motor (IPMSM), the working point is difficult to calculate and the saturation of current regulators may lead to losing control. Linear field-weakening control (LFC) of IPMSM is proposed to control both torque and current in wide speed range applications and LFC can prevent ...

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

MTPA and Field Weakening Control of Synchronous Reluctance motor
2016 9th International Conference on Electrical and Computer Engineering (ICECE), 2016An improved algorithm for MTPA (Maximum Torque Per Ampere) and Field Weakening operation which is suitable for implementation with Field Oriented Control, has been proposed for the Synchronous Reluctance motor (SynRel) for high dynamic performance. The proposed method overcomes the problem of excessive current flow into the machine while generating the

Thermal aspects of field weakening implementation for robotics applications
2005 European Conference on Power Electronics and Applications, 2005The paper describes the implementation and tests of the field weakening algorithm for robotics applications. The tests have been done both in a test bench as well as in a robot prototype. The emphasis on the analysis has been put on the thermal behaviour of the motor at higher speeds, as this is an important limiting factor when operating in a ...

An Enhanced Field-Weakening Algorithm for BLDC Motor Drives
2018 4th International Conference on Electrical Energy Systems (ICEES), 2018Due to significant features of BLDC motor drives, they are being used in various applications. The implementation of BLDC motors is feasible because of the progress of innovations in Permanent magnet (PM) which give high power density, efficiency, and torque for Brushless DC motors. When compared to other motors of equivalent power BLDC motors has less

Control System with Field Weakening of Synchronous Motor Drive
2020 IEEE Problems of Automated Electrodrive. Theory and Practice (PAEP), 2020Improving of dynamic performance of a control system of a synchronous drive with field weakening is shown. The controllers of the angular speed of the rotor of a synchronous machine, d and q components of the stator current of the control system have synthesized using the concept of inverse dynamics problems and minimization of local functionalities in

Control of induction motors in the field weakening region
Proceedings of 1995 34th IEEE Conference on Decision and Control, 2002In this paper we extend the results on observerless passivity-based control of induction motors reported by Espinosa-Ortega (1994) and Ortega et al. (1995) to include the case of rotor flux norm tracking. This extension from regulation to tracking of rotor flux norm is important for practical implementation problems of the controllers where inverter ...

Microprocessor-based DC motor drive with spillover field weakening
IEEE Transactions on Industrial Electronics, 1991A microprocessor-based speed control scheme for a separately excited DC motor fed from a DC source, which incorporates both armature-voltage control and spillover field weakening to provide smooth and precise control from standstill to speeds well above the base value, is described.

Field-weakening method for v/f -controlled hoist drive
2011 IEEE International Electric Machines & Drives Conference (IEMDC), 2011This paper presents a field-weakening control method for V/f-controlled hoist drives. The method is based on the power limitation, which enables a load-dependent maximum speed without load measurement. In order to avoid the pull-out point of the hoist motor, the acceleration is halted if the motor input power exceeds a predefined limit. In addition, an

Distortion voltage compensation in field-weakening region of IPMSM
2017 IEEE International Electric Machines and Drives Conference (IEMDC), 2017An optimal field weakening (FW) control for interior permanent magnet synchronous motor (IPMSM) considering the nonlinearities of IPMSM and inverter is presented in this paper. Nonlinearities of inverter cause distortion voltage (DV) which considerably affects the efficiency of IPMSM in FW region. In FW operation, the efficient utilization of available
