On 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 کاملAssessment of direct torque control for induction motor drives
Among all control methods for induction motor drives, Direct Torque Control (DTC) seems to be particularly interesting being independent of machine rotor parameters and requiring no speed or position sensors. The DTC scheme is characterized by the absence of PI regulators, coordinate transformations, current regulators and PWM signals generators. In spite of its simplicity, DTC allows a good to...
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 کاملDirect Torque Control Technique in Induction Motor Drives - a Review
The aim of this paper is to review the origin and developments of direct torque control (DTC), an advanced control technique of induction motor drives yielding superior performance. The direct torque control is one of the excellent control strategies available for torque control of induction machine. It is considered as an alternative to field oriented control (FOC) technique. The DTC is charac...
متن کاملstator 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...
