The optimal torque control of a synchronous machine is a classical problem. This paper presents an alternative to SVM (Space Vector Modulation which belongs to PWM approaches) based upon direct boolean control. The result is a predictive method allowing an optimal torque control of the synchronous machine. A comparison between both approaches will be proposed . Copyright  2002 IFAC

This paper proposes design and simulation of Direct Torque Control of Induction Motor drive system is to minimize stator current distortion, electromagnetic torque and flux ripples. In this paper, Fuzzy Logic Controllers are proposed to replace the classical PI torque and flux controllers to achieve desired torque and flux with zero steady state error and also with good dynamic tracking and fas...

For many industrial applications that including electric motor, selecting of the appropriate motor type is keypoint for the application success and efficiency. This paper presents a comparative performance evaluation between direct torque controlled Brushless AC and Brushless DC motors which have been considered as traction motor on electric vehicles. Moreover, a short review to brushless AC an...

It is fairly well known that direct torque control (DTC) exhibits fast dynamic torque response, a property that originates in the fact that torque and flux is directly controlled by instantaneous space voltage vector, unlike field-oriented control. For this reason direct torque control gradually has been used in the field, eliciting quick response and high efficiency since its introduction in t...

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...

This paper presents Electric Vehicle (EV) propulsion using a three phase squirrel cage induction motor. The motor control at different operating conditions is carried out by a direct torque control technique with an energy optimization strategy. The operating flux of the motor is chosen optimally using model based control strategy. Simulation tests have been carried out using MATLAB SIMULINK to...
