“…So, demagnetisation before dL dθ region is negative and the extended voltage supply at the starting of each phase is ensured. The implementation of soft switching is much complex and is not required for low power applications (Lin et al, 2012). High performance system requires adaptive speed and current control strategies (Bayoumiet al, 2009).…”

Demand for brushless and commutator-less motor drives is increasing day by day for industrial applications. So improvement in switched reluctance motor (SRM) drives remains an important research area due to cheap and maintenance free motor construction. In literature, various converter topologies and their control strategies are described, however the C-dump-based converter topologies have gained interest owing to its ability to retrieve the stored magnetic energy. This can be further utilised to achieve desirable performance characteristics. The paper addresses the development of a drive system for a four phase, 8/6 switched reluctance motor. The drive system consists of a power circuit and its control scheme. The power components are designed for a 4-phase, 3 hp, 8/6 SRM which is used to obtain the experimental results. A simple PI-based speed control scheme is implemented which is suitable for low power applications such as cooling fan, blower, etc. A C-dump-based converter is proposed which allows reduction of switching losses, especially in the low speed range and it eliminates energy intake from the source during energy discharge process.

“…A switched reluctance motor (SRM) has the following advantages: rigid and simple structure, simple converter circuit with fault tolerance, high starting torque, premium speed regulation, etc. However, the SRM suffers from high ripples in the output torque due to the discrete nature of the torque production and high nonlinear characteristics that complicate the analysis as well as the control of the motor [1][2][3][4][5].…”

Saliency and nonlinear magnetization characteristics of switched reluctance motor (SRM) are causes for its poor performance regarding torque ripples. This paper presents an innovative methodology based on a water cycle algorithm (WCA) for SRM speed control with minimum torque ripples and maximum torque per ampere. WCA enhances the dynamic and steady-state performance of this motor by optimizing a multiobjective function consisting of three parts. The first part is the integral time absolute error (ITAE) of motor speed with respect to a desired reference speed, the second part is an index for a motor torque smoothness factor (TSF), and the third part is the torque per ampere ratio (TAR). The desired output of WCA is the appropriate gains of the PI speed controller and optimum turn on and off angles of the H-bridge driving circuit. The results obtained from WCA are used to construct an adaptive controller-based artificial neural network (ANN) to automatically tune the gains of the PI speed controller and the turn on and off angles. The ANN controller ensures superior steady-state and dynamic motoring operation over a wide range of speed commands and different loads. The results of WCA are verified by other well-known meta-heuristic optimized techniques, such as the Genetic algorithm (GA). The suggested method exhibits an excellent speed transient response in addition to minimum torque ripples and maximum TAR.

“…Hence, it possesses high application potential, particularly for high-speed driving and operating at high-temperature and high humidity environments. The studies made in [3][4][5][6] indicated that SRM possesses driving characteristics comparable to permanent-magnet synchronous motors in cooling fan and electric vehicles. However, SRM also suffers from many inherent drawbacks: (i) non-linear winding current and developed torque dynamics and (ii) higher torque ripple, vibration and acoustic noise owing to its doubly salient structure and non-ideal square-wave winding current [2,7].…”

Adequate commutation instant setting and tuning in accordance with varied operating conditions are required for achieving good winding current and developed torque responses for a switched-reluctance motor (SRM) drive. This study presents a dynamic commutation shift controller (DCSC) based on DC-link current ripple minimisation for SRM drives. A single-phase bridgeless switch-mode rectifier (SMR) fed SRM drive is established for making the performance evaluation. The robust control schemes of the SMR and SRM drive are properly designed to yield satisfactory dynamic and static operation characteristics. The boosted and well-regulated DC-link voltage is established from the mains to enhance the SRM drive performance under high speeds. In addition, good line drawn power quality with high efficiency is obtained simultaneously by the bridgeless SMR front-end. In the developed DCSC, the observed DC-link ripple current is processed and used to determine the commutation shift angle automatically. Some measured results are provided to demonstrate the performance of the established SMR-fed SRM drive under the commutation using the proposed DCSC.
