Nonlinear Load-Adaptive MIMO Controller for DC Motor Field Weakening

Electric Machines & Power Systems, 2000
Control problem of field weakening for a separately excited DC motor system, modeled in nonlinear differential equations, is tackled in this paper. A novel constant power field weakening controller, based on nonlinear load-adaptive multi-input multi-output (MIMO) linearization technique, is developed to achieve high-performance speed tracking through ...

Nonlinear MIMO Speed Sensorless Controller for DC Motor Field Weakening

Electric Machines & Power Systems, 2000
This paper addresses speed control of a separately excited DC motor (SEDCM) in nonlinear field weakening region. Input output linearization (IOL) technique is used to deal with the motor system with considerable nonlinearity, and a nonlinear multi-input multi-output (MIMO) speed tracking controller is developed for constant power field weakening.

Torque Closed-Loop Flux-Weakening Control of IPMSM Based on Search Coils

IEEE transactions on industrial electronics (1982. Print)
A torque closed-loop flux-weakening (FW) control strategy of interior permanent magnet synchronous motor (IPMSM) based on search coils (SCs) is proposed in this article. The proposed strategy adopts a three-closed-loop control structure, where the torque

Induction motor sensorless vector control in the field weakening region

IEE Seminar on Advances in Induction Motor Control, 2000
Speed-sensorless control of induction motor drives has attracted considerable attention in recent past, with a vast amount of effort directed towards providing an accurate speed estimate in the vicinity of zero speed. The problem of speed estimation in the field weakening region has stayed to a large extent beyond the scope of interest.
