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...

This paper reports on advances in the design and development of a high-performance direct-drive joint for robotics and automation. The joint integrates a motor, a torque sensor and joint bearings. The key design aspects of the motor, such as the armature, motor housing, bearing arrangement and sensors, are detailed. The description of a dynamometer testbed with a hydraulic active load used for ...

recently, transverse flux permanent magnet generators (tfpmgs) have been proposed as a possible generator in direct drive variable speed wind turbines due to their unique merits. generally, the quality of output power in these systems is lower than multi stage fixed speed systems, because of removing the gears, so it’s important to design these kinds of generators with low ripple and lowest har...

. This paper proposes the three level diode clamped multilevel inverter fed direct torque control of induction motor. The proposed multilevel inverter has the advantages of fewer harmonic in the output and low torque ripples. The switching table direct torque control scheme is adopted due to the simplicity of the control algorithm. The PI speed controller is used in the outer loop. To demonstra...

This paper proposes a new consequent-pole permanent magnet vernier machine (CPMVM), which can be regarded as combination of two conventional CPMVM with opposite polarities. Based on the simplified axial magnetic circuit model, it is verified that proposed reduce unipolar leakage flux. In order to torque ripple and improve output machine, flux barrier placed rotor machine. Then, parameters are o...

This paper addresses a basic control issue in switched reluctance motor (SRM) drives—the production of a ripple-free torque. Simple and largely model-independent conventional supply waveforms are not able to satisfy this requirement. The goal of this paper is to improve SRM dynamical performance by compensating for motor nonlinearities, while maintaining the robustness of conventional methods. ...
