Tire forces are at the heart of the dynamic qualities of vehicles. With the advent of electric vehicles the precise and accurate control of the traction and braking forces at the individual wheel becomes a possibility and a reality outside test labs and virtual proving grounds. Benefits of individual wheel torque control, or torque-vectoring, in terms of vehicle dynamics behavior have been well...

The synchronous reluctance motor (SynRM) has many advantages over other ac motors. For example, its structure is simple and rugged. In addition, its rotor does not have any winding or magnetic material. Prior to twenty years ago, the SynRM was regarded as inferior to other types of ac motors due to its lower average torque and larger torque pulsation. Recently, many researchers have proposed se...

background and aims. the aim of this study was to assess the opening torque of grooved and non-grooved screws made of shape memory alloys (sma) for fixation of mandibular fractures. materials and methods. in this in vitro study the opening torques of ten sma screws with grooves and ten sma screws without grooves were compared in 20 holes (10 holes for grooved screws and 10 holes for non-grooved...

This paper proposes a novel hybrid control of induction motor, based on the combination of the direct torque control DTC and the backstepping one, optimized by Genetic Algorithm (GA). First the basic evolution of DTC is explained, where the torque and stator flux are controlled by non linear hysteresis controllers which cause large ripple in motor torque at steady state operation. A Backsteppin...

The main objective of this paper is to improve the performance of direct torque control of induction motor using three-level inverter without affecting its simplicity. The basic switching table based direct torque control of induction motor using two-level inverter is first...

In this study, direct torque control (DTC) of induction motor is evaluated based on space vector modulation (SVM).DTC is a method to control machine with utilizing torque and flux of motor controlled.Direct Torque Control (DTC) is known to produce fast response and robust control in ac adjustable speed drives. However, in the steady-state operation, notable torque, flux and current pulsations o...

This paper presents a design method of a torque control strategy for parallel hybrid electric vehicles (PHEV) by using fuzzy logic. Taking the driver command, the state of charge (SOC) of the battery, and the motor/generator speed as inputs, a fuzzy controller and relevant fuzzy rules have been developed to effectively determine the torque distribution between electric motor (EM) and internal c...

Induction machines are widely employed in industries due to their rugged structure, high maintainability and economy than DC motors. There has been constant development in the induction motor drive system and their implementation in industrial applications. The improvement of switching speed of power electronic devices has enabled control techniques which possess high switching frequency and fe...

Due to the small inductance, modulation of three phase inverter induces serious torque ripple. In addition, the increase in modulation frequency is limited by the processor speed. Therefore, the traditional torque control approaches are not suitable. In order to solve the aforementioned problems, a new instantaneous torque control method for small inductance brushless dc motor is proposed by im...
