Prediction Algorithm for Torque Ripple Reduction in Dtc-based Drives
Abstract – In direct torque control, the selection of an applied voltage vector is based on the measured parameters at the beginning of the sampling period. The delay between the measurement and the application of the voltage vector is the origin of an extra torque ripple. In this paper, a new predictive controller is proposed for compensating this delay and reducing the torque ripple. The stat...

متن کاملReduction of Torque Ripple in Trapezoidal PMSM using Multilevel Inverter
Permanent Magnet Brushless DC motors are used wide applications in industries due to their high power density and easy to control. These motors are generally controlled using a three phase power semiconductor bridge. For starting and to provide proper commutation sequence to turn on the power devices in the inverter bridge the rotor position sensors are required. Based on the rotor position, th...

This paper analyzes the reason of Low-speed vibration in an electric vehicle, builds the mathematical equation of powertrain torsional vibration. Then, the model of torque ripple considering non-sinusoidal magnetic field distribution is built, orders and frequencies of torque ripple in PMSM is predicted. According to the relationship between the torsional vibration in low-speed of the electric ...
متن کاملA family of switching control strategies for the reduction of torque ripple in DTC
In this paper, we are interested in design of switching control strategies which, as in the case of classical direct torque control (DTC), aim to directly regulate two outputs: torque and flux amplitude. A criterion in terms of the error and/or the prediction in one-step-ahead on these outputs is proposed to design the switching sequence. As a result, a control vector, i.e., the switch position...
