An inherent torque ripple characterizes switched reluctance technology from conventional technology. The ultimate aim of this paper is to reduce the torque ripple of the switched reluctance motor drive using genetic neural network controller based direct torque scheme. In the proposed controller network appropriate bits of data are chosen for training and testing. The proper selection of the learning rate and momentum will help in weight adjustment. Here the error is reduced which proves that the selection of voltage vectors from the vector table is precise and its results in better torque response over a wide range of speed. The simulation results reveal that the torque ripples vary between 3.25% to 1.7% for the variation in load torque and the drive speed. The experimental results for the proposed controller reveal that the torque ripple varies between 3.7% to 2.1%. Both the simulation and hardware results illustrate the efficiency of the controller.
Now a day Electric vehicles (EV) are called future vehicles in place of internal combustion engines because of their working with pollution free and more efficient. This paper reviews various control strategies of induction motor drives (IMD) for EV applications. Efficiency and performance are the major considerations in selecting control algorithms for induction motor drives. Basically there are scalar control and vector control methods for IMDs. Scalar control technique has drawback of low performance. Conventional direct torque control (DTC) technique is one of the most preferable control technique for controlling torque and flux independently. But due the lower switching frequency in direct torque control leads to more flux ripple and torque ripples and it leads lower performance of induction motor drives.
An inborn torque swell portrays changed hesitance innovation from traditional innovation. A definitive target of this paper is to minimize the torque wave of the exchanged hesitance engine drive utilizing Artificial Network Fuzzy Inference System based direct torque conspire. In the proposed controller arrange proper bits of information are picked for preparing and testing. The best possible choice of the learning rate and energy will help in weight change. The Intelligent controller gives high power over motor torque and speed, lessens rise time just as overshoot. Here the blunder is decreased which demonstrates that the determination of voltage vectors from the vector table is exact and its outcomes in better torque reaction over a wide scope of speed. The reenactment results uncover that the torque swells fluctuate between 3.75% to 2.25% for the variety in load torque and the drive speed. The experimental results for the proposed controller reveal that the torque ripple varies between 3.9% to 2.4% for the variation in speed. Both the recreation and equipment results delineate the effectiveness of the controller.
