“…Moreover, a RLSRM was presented to integrate rotating and linear motion together [10], [11] but a coupling effect has occurred when both rotary and linear motion are produced by the same coils. Therefore, the decoupled control methods have been investigated in [12], [13].…”

A decoupled two-degree of freedom (2-DOF) in the linear and rotary directions of a motor based on switched reluctance principle is investigated. First, the structure of the motor is introduced, and the design procedure for the main parameters of the motor is elaborated. Also, the magnetic decoupled structure for the motor is illustrated. Secondly, a magnetic circuit analysis is given to explain the decoupled structure, followed by simulation finite element method (FEM), including the inductance profiles, force and torque outputs etc. Meanwhile, control method for this motor is provided by using two proportional-integral-derivation (PID) controllers to regulator the linear position and the rotating angle independently. Linear force distribution function (FDF) and torque sharing function (TSF) are employed by the control system. Thirdly, experimental results involving the force and torque measurements, linear position and rotating angle responses are obtained, under specific loads and without a load. The motor is capable of realizing high-precision rotary and linear tracking within 0.3 ̊ and 500 μm under specific loading conditions, respectively. It suggests that the proposed structure can readily realize decoupled control proposed by this paper.

“…Lim and Krishnan [34] and others ( [35], [32], [18], [17], [9], [43]) has used a LF configuration as a model to study for its mechanical stability thereby optimize its performance characteristics. Liu and Kuo [37], Baoming et al [5] and Liu et al [40] has used a TF configuration to drive a wagon on wheels which obtained promising results in application. The LSRM designs based on an open RSRM structure, consists of a single primary and secondary ( [53], [54], [5], [32]).…”

“…Similarly, when the translator houses the windings, the configuration is called an active translator or primary mover. Liu and Kuo [37] developed a LSRM for wagon wheel which uses an active translator assembly, the likes of which has been popularly adopted in several applications ( [34], [35], [29], [56], [39]). In applications such as material handling system where the displacement is short, an active stator configuration is preferred.…”

“…A popular method of developing an analytical model is the reluctance network model from which magnetic flux linkages are estimated. Significant development in such network models ( [37], [29], [17], [9], [43], [6], [49], [51], [47], [1]) have resulted in better accuracy. However, finite element analysis still remains the most accurate method to obtain performance characteristics of the machine.…”

“…Development of control algorithms obtained a smoother operation by reducing cogging or ripple force, often experienced in a variable reluctance machine. This accelerated their application in several fields ranging from elevator drives [34], [35], generators [57], transportation rails ( [37], [5], [29]) ocean wave energy harnesser [56], actuators [12], driver for automatic door [18], medical applications [41] only to name a few. The present work discusses the various flexibility in configuration, algorithms of design, tools of analysis and adopted control methodologies of LSRM, in brief.…”

Summary. Switched reluctance motors have been extensively studied by researchers for their unparalleled advantages in many applications. The linear versions have been developed around the world in the last couple of decades because of attributes similar to that of rotary switched reluctance motor(RSRM). Owing to their frugal design, robust built and high force density, the linear switched reluctance motor (LSRM) has had significant stages of development and optimization. The flexibility in design and operation makes LSRM a prime contender for any linear motor-actuator application. This paper provides a bird's eye view across its developmental stages and its various aspects in design, analysis and control. The following content discusses the salient points of research and the contribution by researchers in this field.
