A new direct torque control strategy for flux and torque ripple reduction for induction motors drive-a Matlab/Simulink model
TL;DR: In this paper, a new direct torque control (DTC) scheme for an induction motor is proposed, which features low torque ripple and low flux ripple by means of space vector modulation (SVM).

A High Performance Permanent Magnet Synchronous Motor Drive by using a Robust Adaptive Control Strategy
TL;DR: In this paper, a robust adaptive control strategy for permanent magnet synchronous motor (PMSM) drive systems is presented. This control scheme is based on a adaptive pole placement control strategy integrated to a sliding mode control scheme.

An EKF-Based Estimator for the Speed Sensorless Vector Control of Induction Motors
TL;DR: In this paper, an extended Kalman filter (EKF) algorithm is proposed to estimate the mechanical uncertainties together with the rotor resistance, R′ r, without injecting high frequency signals, and the rotor flux, angular velocity and stator currents with no apriori knowledge on the states and initial values taken as zero.

Dual-frequency braking in AC drives
M. Rastogi,P.W. Hammond +1 more
TL;DR: In this paper, a method to obtain braking torque in non-regenerative AC drives without the need for additional power circuits is presented, where braking energy is absorbed from the rotating inertia at the applied frequency and is dissipated in the motor at a second lossinducing frequency.
