“…Yao et al applied a fuzzy neural network modeling to learn the nonlinear static position-torque-current and flux linkage characteristics for torque control of the SRA [74]- [75]. Then, torque distribution function was used to calculate the phase torque and the ANFIS inverse torque model to obtain optimize current waveform.…”

This paper presents the review of design variables optimization and control strategies of a Linear Switched Reluctance Actuator (LSRA). The introduction of various type of linear electromagnetic actuators (LEA) are compared and the advantages of LSRA over other LEA are discussed together with the type of actuator configurations and topologies. The SRA provides an overall efficiency similar to induction actuator of the similar rating, subsequently the friction and windage losses are comparable but force density is better. LSRA has the advantage of low cost, simple construction and high reliability compare to the actuator with permanent magnet. However, LSRA also has some obvious defects which will influence the performance of the actuator such as ripples and acoustic noise which are caused by the highly nonlinear characteristics of the actuator. By researching the design variables of the actuator, the influences of those design variables are introduced and the detail comparisons are analyzed in this paper. In addition, this paper also reviews on the control strategies in order to overcome the weaknesses of LSRA. Keyword:Actuator INTRODUCTIONLinear electromagnetic actuators (LEA) is a mechanism that generate linear motion due to the interactions of the magnetic fields and electromagnetic thrust. The major advantage of electromagnetic actuators over the conventional actuators is that it is almost maintenance free which is due to the absence of mechanical part such as gears The typical design of LEA can be characterized as three topologies: (i) Planar Single Sided; (ii) Planar Double Sided; (iii) Tubular. By comparison, the tubular topology of LEA has greater force density compare to planer topology actuator due to lesser flux leakage and tubular topology actuator minimized the stray magnetic field in the direction of travel along the stator and mover part [5]. Hence, the thrust force and

“…In SRM with many stator/rotor poles or with a large salient pole width, the torque ripple is not extremely large. In such cases, a nearly flat instantaneous torque can be obtained by using multipulse control to provide a flat-top trapezoidal wave current in the appropriate rotor positions and conduction intervals [7][8][9][10][11], which is called trapezoidal current control. In most control schemes of this kind, the flat-top current is calculated by approximation functions, and the actual current is controlled by tracking the reference waveform thus obtained.…”

SUMMARYThis paper presents a new instantaneous current control to obtain an instantaneously flat torque waveform with smaller torque ripples of switched reluctance motors (SRMs). The proposed current control is based on table lookup. By geometric insights for the machine and finite element method based analysis, ideal current profiles for the flat torque are generated. Some simulation results are presented to demonstrate the validity of the proposed control, which are verified by experiment.
