This paper proposes a novel Hermite neural network-based second-order sliding-mode (HNN-SOSM) control strategy for the synchronous reluctance motor (SynRM) drive system. The proposed HNN-SOSM is nonlinear vector consisting of speed loop and current loop. adopts composite controller, which composed three components: 1) standard super-twisting algorithm-based SOSM (STA-SOSM) controller achieving ...

Design, optimization, and performance analysis of a three-phase field-excited flux switching (FEFS) motor to be employed for the future hybrid electric vehicle (HEV) drive applications is investigated in this paper. The stator of designed motor made of electromagnetic steels is composed of unique field mmf source and armature coils while a rotor is made of iron stack. This design has been evalu...

Permanent Magnet Synchronous Motors (PMSM) are widely used in industrial drives due to their high power density, high torque-toinertia ratio, small torque ripple and precise control at low speed range, possibility to torque control at zero speed, high efficiency and small size. To exploit presented advantages, a vector control should be used. Vector control allows the drive a good dynamic, effe...

Two types of prime movers are continuously applied for rotating machinery: mechanical and electric drives. This tutorial focuses on electric drives, which are actually composed of separate components: electric motor, frequency converter (optional), and electric network including transformers. The main aim of this tutorial is to explain the phenomena of electric drives related to the torsional v...

In many Sensorless Field Oriented Control schemes for Induction Motor (IM) drives the flux is estimated by means of the measured motor currents and the control reference voltages. In most of cases, the flux estimation is based on the integral of the back-EMF voltages. The inverter nonlinear errors (dead-time and on-state voltage drops) introduce a distortion in the estimated voltage that reduce...

This letter proposes a general single-sensor active damping framework for LCL -equipped high-speed permanent magnet synchronous machines. By the proposed method, arbitrary assignment and stability resonance within Nyquist frequency are achieved with only inverter-current feedback or motor-curre...

<p>This paper presents a real-time emulator of dual permanent magnet synchronous motor (PMSM) drive implemented on field-programmable gate array (FPGA) board for supervision and observation purposes. In order to increase the reliability drive, sensorless speed control method is proposed. This allows replacing physical sensor while guaranteeing satisfactory operation even in faulty conditi...

Many researches have been carried out to induction motors for starting, braking, speed reversal and speed control, because they are relatively cheap, reliable and rugged machines due to absence of slip rings or commutators. Induction motors exhibit highly coupled, nonlinear time varying system which is difficult to control since some state variables are difficult to be measured. However, recent...

The electrification of loader designs can utilise several power motor types. Hence, this study investigates the operational performance pure electric-powered loaders matched with three types motors. Firstly, for ZL08 loader, it is proposed that a structure adopts two motors to drive walking and hydraulic systems separately. Secondly, dynamic parameters were matched, then, joint vehicle dynamics...
