stator resistance estimation in direct vector control for high performance torque controlled induction motor drives
sensorless speed torque control of induction machines has been widely used in many industrial applications. the simple method of direct vector control can provide tacholess control as well as more complex approaches. in this method, the motor flux can be obtained by measuring voltage and current and integrating motor back electromotive force. the only required motor parameter is stator resistan...
متن کاملOn Line Determination of Optimal Hysteresis Band Amplitudes in Direct Torque Control of Induction Motor Drives
In conventional direct torque control (DTC) of induction machines, undesirable flux and torque ripples are produced. These occur since non of the selected inverter's voltage vectors are able to generate the exact voltage required to produce the desired changes in the electromagnetic torque and stator flux linkage in most of the switching instances. In addition, when direct torque control is imp...
متن کاملPerformance Improvement for Direct Torque Control Induction Motor Drives
This paper presents the modified integrator which we can use in the controlling scheme of an induction motor (IM). The modification tends to some advancement in direct torque control of induction motor. The undesirable variations which occur in the form of offset, gain error, etc can be eliminate by means of the involvement of the new integrator in the direct torque and flux control (DTFC) meth...
متن کاملTorque Control of Brushless Direct Current Motor Drives Using Single Current Sensor with High Reliability
Due to the simple structure, high torque density, low maintenance, and high efficiency, brushless direct current (BLDC) motors are widely used in automation and industrial applications. A control strategy based on single current sensor is proposed for a four-switch three-phase BLDC motor system to lower cost and improve reliability. The whole working process of the BLDC motor is divided into si...
