This paper proposes a method that combines random forest technology (RF) and genetic algorithm (GA) for optimal design of traction motors electric vehicles (EVs). The target motor is permanent magnet assisted synchronous reluctance (PMa-SynRM), which the goal to increase average torque efficiency while reducing total harmonic distortion (THD) line-to-line back electromotive force (LtoL BEMF) ri...

Optimized shaping of the stator current in the switched reluctance motor drive can be used to mitigate electromagnetic torque ripple and decrease the rms current. Previously, optimal current waveshaping has been based upon defining the optimal current waveform as a set of discrete points and interpolating intermediate points. In this work, an alternate approach is employed in which the current ...

The induction motors are indispensable motor types for industrial applications due to its wellknown advantages. Therefore, many kind of control scheme are proposed for induction motors over the past years and direct torque control has gained great importance inside of them due to fast dynamic torque response behavior and simple control structure. This paper suggests a new approach on the direct...

Electric vehicle (EV) due to its running zero emission, sustainability and efficiency is of interest for future transportation. In-wheel technology has been one of the main research concentration points in last decade. BLDC motor is on demand for in-wheel application because of its high efficiency, torque/speed characteristics, high power to size ratio, high operating life and noiseless operati...

In this paper, two intelligent direct torque control strategies are compared with the classical direct torque control (C-DTC) scheme, namely neural network control (NNC) and neuro-fuzzy control (NFC) are introduced to replace the hysteresis comparators and lookup table of the C-DTC for pulse width-modulation-inverter-fed induction motor drive, to solve the problems of torque ripple and inconsta...

Noise reduction in axial piston pumps has been attempted by many researchers with different design approaches and techniques. However, most traditional structures on valve plate for noise reduction are at the cost of efficiency to different extent. In this article, a new distribution method with pressure equalization mechanism composed of check valve and pressure recuperation chamber is discuss...

In recent days switched reluctance motor is widely used for numerous industrial applications due to its simple structure, minimum cost and maximum efficiency. Regardless of exclusive benefits the (SRM), acoustic noise this high it important accomplish more analysis on lessening, which primary goal paper. The major causes in a SRM are torque ripple radial magnetic force. Since force highly influ...

This paper considers direct torque control strategies in induction motor drive to minimize torque ripples. Spacevector modulation and modified space vector control concept is implemented to design the controller. Basic DTC method suffers from torque ripples problem and switching frequency variation.[1] Torque ripples are minimized using space vector modulation technique but execution time in th...

a few papers have been interested by the fixed switching frequency direct torque control fed by direct matrix converters, where we can find just the use of direct torque controlled space vector modulated method.
